b4184c666c ipq40xx: add support for Linksys WHW01 v1
This patch adds support for Linksys WHW01 v1 ("Velop") [FCC ID Q87-03331].

Specification
-------------

SOC:             Qualcomm IPQ4018
WiFi 1:          Qualcomm QCA4019 IEEE 802.11b/g/n
WiFi 2:          Qualcomm QCA4019 IEEE 802.11a/n/ac
Bluetooth:       Qualcomm CSR8811 (A12U)
Ethernet:        Qualcomm QCA8072 (2-port)
SPI Flash 1:     Mactronix MX25L1605D (2MB)
SPI Flash 2:     Winbond W25M02GV (256MB)
DRAM:            Nanya NT5CC128M16IP-DI (256MB)
LED Controller:  NXP PCA963x (I2C)
Buttons:         Single reset button (GPIO).

Notes
-----

There does not appear to be a way to trigger TFTP recovery without entering
U-Boot. The device must be opened to access the serial console in order to
first flash OpenWrt onto a device from factory.

The device has automatic recovery backed by a second set of partitions on
the larger of the two SPI flash ICs. Both the primary and secondary must
be flashed to prevent accidental rollback to "factory" after 3 failed boot
attempts.

Serial console
--------------

A serial console is available on the following pins of the populated J2
connector on the device mainboard (115200 8n1).

(<-- Top of PCB / Device)

  J2
  [o o o o o o]
       |   | |
       |   |  `-- GND
       |    `---- TX
       `--------- RX

Installation instructions
-------------------------

1. Setup TFTP server with server IP set to 192.168.1.236.
2. Copy compiled `...squashfs-factory.bin` to `nodes-jr.img` in tftp root.
3. Connect to console using pinout detailed in the serial console section.
4. Power on device and press enter when prompted to drop into U-Boot.
5. Flash first partition device via `run flashimg`.
6. Once complete, reset device and allow to power up completely.
7. Once comfortable with device upgrade reboot and drop back into U-Boot.
8. Flash the second partition (recovery) via `run flashimg2`.

Revert to "factory"
-------------------

1. Download latest firmware update from vendor support site.
2. Copy extracted `.img` file to `nodes-jr.img` in tftp root.
3. Connect to console using pinout detailed in the serial console section.
4. Power on device and press enter when prompted to drop into U-Boot.
5. Flash first partition device via `run flashimg`.
6. Once complete, reset device and allow to power up completely.
7. Once comfortable with device upgrade reboot and drop back into U-Boot.
8. Flash the second partition (recovery) via `run flashimg2`.

481339a042 uboot-imx: fix wrong make flags overriding
Buidbots are currently choking on the following compile error:

 In file included from tools/aisimage.c:9:
 include/image.h:1133:12: fatal error: openssl/evp.h: No such file or directory
  #  include <openssl/evp.h>
             ^~~~~~~~~~~~~~~
 compilation terminated.

This is caused by a complete overriding of make flags which are provided
correctly in `UBOOT_MAKE_FLAGS` variable, but currently overriden
instead of extended. This then leads to the usage of build host include
dirs, which are not available.

Fix it by extending `UBOOT_MAKE_FLAGS` variable in all device recipes.

057bac2e1f uboot-fritz4040: Add support for Toshiba NAND
From Andreas Böhler:

"Some revisions of the FRITZ!7530 use a Toshiba NAND with 8 bit ECC
in contrast to the Macronix NAND with 4 bit ECC.".

Uboot needs to know this in order to have a chance to load from
the NAND.

580723e86a realtek: add support for ZyXEL GS1900-16
The ZyXEL GS1900-16 is a 16 port gigabit switch similar to other GS1900 switches.

Specifications
--------------
* Device:    ZyXEL GS1900-16
* SoC:       Realtek RTL8382M 500 MHz MIPS 4KEc
* Flash:     16 MiB Macronix MX25L12835F
* RAM:       128 MiB DDR2 SDRAM Nanya NT5TU128M8HE
* Ethernet:  16x 10/100/1000 Mbps
* LEDs:      1 PWR LED (green, not configurable)
             1 SYS LED (green, configurable)
             16 ethernet port link/activity LEDs (green, SoC controlled)
* Buttons:   1 "RESET" button on front panel
* Power      120-240V AC C13
* UART:      1 serial header (J12) with populated standard pin connector on
             the right back of the PCB.
             Pinout (front to back):
             + Pin 1 - VCC marked with white dot
             + Pin 2 - RX
             + Pin 3 - TX
             + PIn 4 - GND

Serial connection parameters:  115200 8N1.

Installation
------------

OEM upgrade method:

* Log in to OEM management web interface
* Navigate to Maintenance > Firmware
* Select the HTTP radio button
* Select the Active radio button
* Use the browse button to locate the
realtek-generic-zyxel_gs1900-16-initramfs-kernel.bin
file amd select open so File Path is update with filename.
* Select the Apply button. Screen will display "Prepare
for firmware upgrade ...".
*Wait until screen shows "Do you really want to reboot?"
then select the OK button
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
   > sysupgrade -n /tmp/realtek-generic-zyxel_gs1900-16-squashfs-sysupgrade.bin
   it may be necessary to restart the network (/etc/init.d/network restart) on
   the running initramfs image.

U-Boot TFTP method:

* Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10).
* Set up a TFTP server on your client and make it serve the initramfs image.
* Connect serial, power up the switch, interrupt U-boot by hitting the
  space bar, and enable the network:
   > rtk network on
* Since the GS1900-16 is a dual-partition device, you want to keep the OEM
  firmware on the backup partition for the time being. OpenWrt can only boot
  from the first partition anyway (hardcoded in the DTS). To make sure we are
  manipulating the first partition, issue the following commands:
  > setsys bootpartition 0
  > savesys
* Download the image onto the device and boot from it:
   > tftpboot 0x84f00000 192.168.1.10:openwrt-realtek-generic-zyxel_gs1900-16-initramfs-kernel.bin
   > bootm
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
   > sysupgrade -n /tmp/openwrt-realtek-generic-zyxel_gs1900-16-squashfs-sysupgrade.bin
   it may be necessary to restart the network (/etc/init.d/network restart) on
   the running initramfs image.

  Flash: 256 MB NAND, 32 MB NOR
  WiFi: QCA9983 2.4 GHz, QCA9984 5 GHz
  Switch: QCA8337
  Ethernet: 5x 10/100/1000 Mbit/s
  USB: 1x USB 3.0 Type-A
  Buttons: WPS, Reset
  Power: 12 VDC, 2.5 A

Ethernet ports:
  1x WAN: connected to eth2
  4x LAN: connected via the switch to eth0 and eth1
          (eth0 is disabled in OEM firmware)

MAC addresses (OEM and OpenWrt):
  fw_env @ 0x00  d4🆎82:??:??:?a  LAN (eth1)
  fw_env @ 0x06  d4🆎82:??:??:?b  WAN (eth2)
  fw_env @ 0x0c  d4🆎82:??:??:?c  WLAN 2.4 GHz (ath1)

  fw_env @ 0x18  d4🆎82:??:??:?e  OEM usage unknown (eth0 in OpenWrt)

  OID d4🆎82 is registered to:
  ARRIS Group, Inc., 6450 Sequence Drive, San Diego CA 92121, US

More info:
  https://openwrt.org/inbox/toh/arris/tr4400_v2

IMPORTANT:

This port requires moving the 'fw_env' partition prior to first boot to
consolidate 70% of the usable space in flash into a contiguous partition.
'fw_env' contains factory-programmed MAC addresses, SSIDs, and passwords.
Its contents must be copied to 'rootfs_1' prior to booting via initramfs.
Note that the stock 'fw_env' partition  will be wiped during sysupgrade.

A writable 'stock_fw_env' partition pointing to the old, stock location
is included in the port to help rolling back this change if desired.

Installation:

- Requires serial access and a TFTP server.
- Fully boot stock, press ENTER, type in:
mtd erase /dev/mtd21
dd if=/dev/mtd22 bs=128K count=1 | mtd write - /dev/mtd21
umount /config && ubidetach -m 23 && mtd erase /dev/mtd23
- Reboot and interrupt U-Boot by pressing a key, type in:
set mtdids 'nand0=nand0'
set mtdparts 'mtdparts=nand0:155M@0x6500000(mtd_ubi)'
set bootcmd 'ubi part mtd_ubi && ubi read 0x44000000 kernel && bootm'
env save
- Setup TFTP server serving initramfs image as 'recovery.bin', type in:
set ipaddr 192.168.1.1
set serverip 192.168.1.2
tftpboot recovery.bin && bootm
- Use sysupgrade to install squashfs image.

This port is based on work done by AmadeusGhost <amadeus@jmu.edu.cn>.

69cef74c67 uboot-mvebu: remove enabled CONFIG_CMD_SETEXPR
We don't need to make sure that we want to have enabled
CONFIG_CMD_SETEXPR by default, since this is already done in U-boot [1].
This was actually needed only for clearfog board [2], which was added in
commit: da0005a6d08ae33d958a6d8a6c0c12dc07b5b2b8 ("uboot-mvebu: add
patch to enable setexpr for clearfog boards) and send to U-boot to fix
it properly. After a while, there was added support for Turris Omnia,
which uses setexpr as well [3], but for this board, there are no fixes
needed in U-boot and that's why we can remove this option here.

It is helpful with shell scripting. If some downstream distributions are
using it, they should correct it in defconfig for related boards.

4891b86538 ramips: add support for YunCore AX820/HWAP-AX820
There are two versions which are identical apart from the enclosure:
  YunCore AX820: indoor ceiling mount AP with integrated antennas
  YunCore HWAP-AX820: outdoor enclosure with external (N) connectors

Hardware specs:
  SoC: MediaTek MT7621DAT
  Flash: 16 MiB SPI NOR
  RAM: 128MiB (DDR3, integrated)
  WiFi: MT7905DAN+MT7975DN 2.4/5GHz 2T2R 802.11ax
  Ethernet: 10/100/1000 Mbps x2 (WAN/PoE+LAN)
  LED: Status (green)
  Button: Reset
  Power: 802.11af/at PoE; DC 12V,1A
  Antennas: AX820(indoor): 4dBi internal; HWAP-AX820(outdoor): external

Flash instructions:
  The "OpenWRT support" version of the AX820 comes with a LEDE-based
  firmware with proprietary MTK drivers and a luci webinterface and
  ssh accessible under 192.168.1.1 on LAN; user root, no password.
  The sysupgrade.bin can be flashed using luci or sysupgrade via ssh,
  you will have to force the upgrade due to a different factory name.
  Remember: Do *not* preserve factory configuration!

MAC addresses as used by OEM firmware:
  use   address            source
  2g    44:D1:FA:*:0b      Factory 0x0004 (label)
  5g    46:D1:FA:*:0b      LAA of 2g
  lan   44:D1:FA:*:0c      Factory 0xe000
  wan   44:D1:FA:*:0d      Factory 0xe000 + 1
The wan MAC can also be found in 0xe006 but is not used by OEM dtb.

Due to different MAC handling in mt76 the LAA derived from lan is used
for 2g to prevent duplicate MACs when creating multiple interfaces.

Installation
------------

OEM upgrade method:

* Log in to OEM management web interface

* Navigate to Maintenance > Firmware > Management

* If "Active Image" has the first option selected, OpenWrt will need to be
  flashed to the "Active" partition. If the second option is selected,
  OpenWrt will need to be flashed to the "Backup" partition.

* Navigate to Maintenance > Firmware > Upload

* Upload the openwrt-realtek-rtl838x-zyxel_gs1900-24hp-v1-initramfs-kernel.bin
  file by your preferred method to the previously determined partition.
  When prompted, select to boot from the newly flashed image, and reboot
  the switch.

* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:

  > sysupgrade /tmp/openwrt-realtek-rtl838x-zyxel_gs1900-24hp-v1-squashfs-sysupgrade.bin

U-Boot TFTP method:

* Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10).

* Set up a TFTP server on your client and make it serve the initramfs
  image.

* Connect serial, power up the switch, interrupt U-boot by hitting the
  space bar, and enable the network:

  > rtk network on

* Since the GS1900-24HP v1 is a dual-partition device, you want to keep the
  OEM firmware on the backup partition for the time being. OpenWrt can
  only be installed in the first partition anyway (hardcoded in the
  DTS). To ensure we are set to boot from the first partition, issue the
  following commands:

  > setsys bootpartition 0
  > savesys

* Download the image onto the device and boot from it:

  > tftpboot 0x81f00000 192.168.1.10:openwrt-realtek-rtl838x-zyxel_gs1900-24hp-v1-initramfs-kernel.bin

6f1efb2898 ath79: add support for Sophos AP100/AP55 family
The Sophos AP100, AP100C, AP55, and AP55C are dual-band 802.11ac access
points based on the Qualcomm QCA9558 SoC. They share PCB designs with
several devices that already have partial or full support, most notably the
Devolo DVL1750i/e.

The AP100 and AP100C are hardware-identical to the AP55 and AP55C, however
the 55 models' ART does not contain calibration data for their third chain
despite it being present on the PCB.

Specifications common to all models:
 - Qualcomm QCA9558 SoC @ 720 MHz (MIPS 74Kc Big-endian processor)
 - 128 MB RAM
 - 16 MB SPI flash
 - 1x 10/100/1000 Mbps Ethernet port, 802.3af PoE-in
 - Green and Red status LEDs sharing a single external light-pipe
 - Reset button on PCB[1]
 - Piezo beeper on PCB[2]
 - Serial UART header on PCB
 - Alternate power supply via 5.5x2.1mm DC jack @ 12 VDC

Unique to AP100 and AP100C:
 - 3T3R 2.4GHz 802.11b/g/n via SoC WMAC
 - 3T3R 5.8GHz 802.11a/n/ac via QCA9880 (PCI Express)

AP55 and AP55C:
 - 2T2R 2.4GHz 802.11b/g/n via SoC WMAC
 - 2T2R 5.8GHz 802.11a/n/ac via QCA9880 (PCI Express)

AP100 and AP55:
 - External RJ45 serial console port[3]
 - USB 2.0 Type A port, power controlled via GPIO 11

Flashing instructions:

This firmware can be flashed either via a compatible Sophos SG or XG
firewall appliance, which does not require disassembling the device, or via
the U-Boot console available on the internal UART header.

To flash via XG appliance:
 - Register on Sophos' website for a no-cost Home Use XG firewall license
 - Download and install the XG software on a compatible PC or virtual
   machine, complete initial appliance setup, and enable SSH console access
 - Connect the target AP device to the XG appliance's LAN interface
 - Approve the AP from the XG Web UI and wait until it shows as Active
   (this can take 3-5 minutes)
 - Connect to the XG appliance over SSH and access the Advanced Console
   (Menu option 5, then menu option 3)
 - Run `sudo awetool` and select the menu option to connect to an AP via
   SSH. When prompted to enable SSH on the target AP, select Yes.
 - Wait 2-3 minutes, then select the AP from the awetool menu again. This
   will connect you to a root shell on the target AP.
 - Copy the firmware to /tmp/openwrt.bin on the target AP via SCP/TFTP/etc
 - Run `mtd -r write /tmp/openwrt.bin astaro_image`
 - When complete, the access point will reboot to OpenWRT.

To flash via U-Boot serial console:
 - Configure a TFTP server on your PC, and set IP address 192.168.99.8 with
   netmask 255.255.255.0
 - Copy the firmware .bin to the TFTP server and rename to 'uImage_AP100C'
 - Open the target AP's enclosure and locate the 4-pin 3.3V UART header [4]
 - Connect the AP ethernet to your PC's ethernet port
 - Connect a terminal to the UART at 115200 8/N/1 as usual
 - Power on the AP and press a key to cancel autoboot when prompted
 - Run the following commands at the U-Boot console:
    - `tftpboot`
    - `cp.b $fileaddr 0x9f070000 $filesize`
    - `boot`
 - The access point will boot to OpenWRT.

MAC addresses as verified by OEM firmware:

use   address     source
LAN   label       config 0x201a (label)
2g    label + 1   art 0x1002    (also found at config 0x2004)
5g    label + 9   art 0x5006

Increments confirmed across three AP55C, two AP55, and one AP100C.

These changes have been tested to function on both current master and
21.02.0 without any obvious issues.

[1] Button is present but does not alter state of any GPIO on SoC
[2] Buzzer and driver circuitry is present on PCB but is not connected to
    any GPIO. Shorting an unpopulated resistor next to the driver circuitry
    should connect the buzzer to GPIO 4, but this is unconfirmed.
[3] This external RJ45 serial port is disabled in the OEM firmware, but
    works in OpenWRT without additional configuration, at least on my
    three test units.
[4] On AP100/AP55 models the UART header is accessible after removing
    the device's top cover. On AP100C/AP55C models, the PCB must be removed
    for access; three screws secure it to the case.
    Pin 1 is marked on the silkscreen. Pins from 1-4 are 3.3V, GND, TX, RX

a05dcb0724 ath79: add support for Yuncore A930
Specification:

- QCA9533 (650 MHz), 64 or 128MB RAM, 16MB SPI NOR
- 2x 10/100 Mbps Ethernet, with 802.3at PoE support (WAN)
- 2T2R 802.11b/g/n 2.4GHz

Flash instructions:

If your device comes with generic QSDK based firmware, you can login
over telnet (login: root, empty password, default IP: 192.168.188.253),
issue first (important!) 'fw_setenv' command and then perform regular
upgrade, using 'sysupgrade -n -F ...' (you can use 'wget' to download
image to the device, SSH server is not available):

  fw_setenv bootcmd "bootm 0x9f050000 || bootm 0x9fe80000"
  sysupgrade -n -F openwrt-...-yuncore_...-squashfs-sysupgrade.bin

In case your device runs firmware with YunCore custom GUI, you can use
U-Boot recovery mode:

1. Set a static IP 192.168.0.141/24 on PC and start TFTP server with
   'tftp' image renamed to 'upgrade.bin'
2. Power the device with reset button pressed and release it after 5-7
   seconds, recovery mode should start downloading image from server
   (unfortunately, there is no visible indication that recovery got
   enabled - in case of problems check TFTP server logs)

9f9477b275 mediatek: Add support for Xiaomi Redmi Router AX6S
Also known as the "Xiaomi Router AX3200" in western markets,
but only the AX6S is widely installation-capable at this time.

SoC: MediaTek MT7622B
RAM: DDR3 256 MiB (ESMT M15T2G16128A)
Flash: SPI-NAND 128 MiB (ESMT F50L1G41LB or Gigadevice GD5F1GQ5xExxG)
WLAN: 2.4/5 GHz 4T4R
2.4 GHz: MediaTek MT7622B
5 GHz: MediaTek MT7915E
Ethernet: 4x 10/100/1000 Mbps
Switch: MediaTek MT7531B
LEDs/Keys: 2/2 (Internet + System LED, Mesh button + Reset pin)
UART: Marked J1 on board VCC RX GND TX, beginning from "1". 3.3v, 115200n8
Power: 12 VDC, 1.5 A

Notes:
U-Boot passes through the ethaddr from uboot-env partition,
but also has been known to reset it to a generic mac address
hardcoded in the bootloader.

However, bdata is also populated with the ethernet mac addresses,
but is also typically never written to. Thus this is used instead.

Installation:
1. Flash stock Xiaomi "closed beta" image labelled
'miwifi_rb03_firmware_stable_1.2.7_closedbeta.bin'.
(MD5: 5eedf1632ac97bb5a6bb072c08603ed7)

2. Calculate telnet password from serial number and login

3. Execute commands to prepare device
nvram set ssh_en=1
nvram set uart_en=1
nvram set boot_wait=on
nvram set flag_boot_success=1
nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=0
nvram commit

4. Download and flash image
On computer:
python -m http.server
On router:
cd /tmp
wget http://<IP>:8000/factory.bin
mtd -r write factory.bin firmware

Device should reboot at this point.

Reverting to stock:
Stock Xiaomi recovery tftp that accepts their signed images,
with default ips of 192.168.31.1 + 192.168.31.100.
Stock image should be renamed to tftp server ip in hex (Eg. C0A81F64.img)
Triggered by holding reset pin on powerup.

A simple implementation of this would be via dnsmasq's
dhcp-boot option or using the vendor's (Windows only)
recovery tool available on their website.

Installation
------------
1. Place *factory.trx on any web server (192.168.1.2 in this example)
2. Connect to the router using telnet shell (no password required)
3. Save MAC adresses to U-Boot environment:
   uboot_env --set --name eth2macaddr --value $(ifconfig | grep eth2 | \
    awk '{print $5}')
   uboot_env --set --name eth3macaddr --value $(ifconfig | grep eth3 | \
    awk '{print $5}')
   uboot_env --set --name ra0macaddr --value $(ifconfig | grep ra0 | \
    awk '{print $5}')
   uboot_env --set --name rax0macaddr --value $(ifconfig | grep rax0 | \
    awk '{print $5}')
4. Ensure that MACs were saved correctly:
   uboot_env --get --name eth2macaddr
   uboot_env --get --name eth3macaddr
   uboot_env --get --name ra0macaddr
   uboot_env --get --name rax0macaddr
5. Download and write the OpenWrt images:
   cd /tmp
   wget http://192.168.1.2/factory.trx
   mtd_write erase /dev/mtd4
   mtd_write write factory.trx /dev/mtd4
6. Set 1st boot partition and reboot:
   uboot_env --set --name bootpartition --value 0
   reboot

Back to Stock
-------------
1. Run in the OpenWrt shell:
   fw_setenv bootpartition 1
   reboot
2. Optional step. Upgrade the stock firmware with any version to
   overwrite the OpenWrt in Slot 1.

MAC addresses

| WLAN_5g   | 32:xx:xx:41:xx:07 |                |
+-----------+-------------------+----------------+
[1]:
a. Label wasb't found neither in factory nor in other places.
b. MAC addresses are stored in encrypted partition "glbcfg". Encryption
   key hasn't known yet. To ensure the correct MACs in OpenWrt, a hack
   with saving of the MACs to u-boot-env during the installation was
   applied.
c. Default Ralink ethernet MAC address (00:0C:43:28:80:36) was found in
   "Factory" 0xfff0. It's the same for all Smartbox Flash devices. OEM
   firmware also uses this MAC when initialazes ethernet driver. In
   OpenWrt we use it only as internal GMAC (eth0), all other MACs are
   unique. Therefore, there is no any barriers to the operation of several
   Smartbox Flash devices even within the same broadcast domain.

41be1a2de2 ath79: add support for Araknis AN-700-AP-I-AC
FCC ID: 2AG6R-AN700APIAC

Araknis AN-700-AP-I-AC is an indoor wireless access point with
1 Gb ethernet port, dual-band wireless,
internal antenna plates, and 802.3at PoE+

this board is a Senao device:
the hardware is equivalent to EnGenius EAP1750
the software is modified Senao SDK which is based on openwrt and uboot
including image checksum verification at boot time,
and a failsafe image that boots if checksum fails

**Specification:**

  - QCA9558 SOC		MIPS 74kc, 2.4 GHz WMAC, 3x3
  - QCA9880 WLAN	PCI card, 5 GHz, 3x3, 26dBm
  - AR8035-A PHY	RGMII GbE with PoE+ IN
  - 40 MHz clock
  - 16 MB FLASH		MX25L12845EMI-10G
  - 2x 64 MB RAM	NT5TU32M16
  - UART console	J10, populated, RX shorted to ground
  - 4 antennas		5 dBi, internal omni-directional plates
  - 4 LEDs		power, 2G, 5G, wps
  - 1 button		reset

  NOTE: all 4 gpio controlled LEDS are viewed through the same lightguide
	therefore, the power LED is off for default state

**MAC addresses:**

  MAC address labeled as ETH
  Only one Vendor MAC address in flash at art 0x0

  eth0 ETH  *:xb art 0x0
  phy1 2.4G *:xc ---
  phy0 5GHz *:xd ---

**Serial Access:**

  the RX line on the board for UART is shorted to ground by resistor R176
  therefore it must be removed to use the console
  but it is not necessary to remove to view boot log

  optionally, R175 can be replaced with a solder bridge short

  the resistors R175 and R176 are next to the UART RX pin at J10

**Installation:**

  Method 1: Firmware upgrade page:

    (if you cannot access the APs webpage)
    factory reset with the reset button
    connect ethernet to a computer
    OEM webpage at 192.168.20.253
    username and password 'araknis'
    make a new password, login again...

    Navigate to 'File Management' page from left pane
    Click Browse and select the factory.bin image
    Upload and verify checksum
    Click Continue to confirm
    wait about 3 minutes

  Method 2: Serial to load Failsafe webpage:

    After connecting to serial console and rebooting...
    Interrupt uboot with any key pressed rapidly
    execute `run failsafe_boot` OR `bootm 0x9fd70000`
    wait a minute
    connect to ethernet and navigate to
    192.168.20.253
    Select the factory.bin image and upload
    wait about 3 minutes

**Return to OEM:**

  Method 1: Serial to load Failsafe webpage (above)

  Method 2: delete a checksum from uboot-env
  this will make uboot load the failsafe image at next boot
  because it will fail the checksum verification of the image

    ssh into openwrt and run
    `fw_setenv rootfs_checksum 0`
    reboot, wait a minute
    connect to ethernet and navigate to
    192.168.20.253
    select OEM firmware image and click upgrade

  Method 3: backup mtd partitions before upgrade

**TFTP recovery:**

  Requires serial console, reset button does nothing

  rename initramfs-kernel.bin to '0101A8C0.img'
  make available on TFTP server at 192.168.1.101
  power board, interrupt boot with serial console
  execute `tftpboot` and `bootm 0x81000000`

  NOTE: TFTP may not be reliable due to bugged bootloader
	set MTU to 600 and try many times

**Format of OEM firmware image:**

  The OEM software is built using SDKs from Senao
  which is based on a heavily modified version
  of Openwrt Kamikaze or Altitude Adjustment.
  One of the many modifications is sysupgrade being performed by a custom script.
  Images are verified through successful unpackaging, correct filenames
  and size requirements for both kernel and rootfs files, and that they
  start with the correct magic numbers (first 2 bytes) for the respective headers.

  Newer Senao software requires more checks but their script
  includes a way to skip them.

  The OEM upgrade script is at
  /etc/fwupgrade.sh

  OKLI kernel loader is required because the OEM software
  expects the kernel to be less than 1536k
  and the OEM upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8035 switch between
  the SOC and the ethernet port.

  For QCA955x series, the PLL registers for eth0 and eth1
  can be see in the DTSI as 0x28 and 0x48 respectively.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x18050028 1` and `md 0x18050048 1`.

  The clock delay required for RGMII can be applied at the PHY side,
  using the at803x driver `phy-mode` setting through the DTS.
  Therefore, the Ethernet Configuration registers for GMAC0
  do not need the bits for RGMII delay on the MAC side.

56716b578e ath79: add support for Araknis AN-500-AP-I-AC
FCC ID: 2AG6R-AN500APIAC

Araknis AN-500-AP-I-AC is an indoor wireless access point with
1 Gb ethernet port, dual-band wireless,
internal antenna plates, and 802.3at PoE+

this board is a Senao device:
the hardware is equivalent to EnGenius EAP1200
the software is modified Senao SDK which is based on openwrt and uboot
including image checksum verification at boot time,
and a failsafe image that boots if checksum fails

**Specification:**

  - QCA9557 SOC		MIPS 74kc, 2.4 GHz WMAC, 2x2
  - QCA9882 WLAN	PCI card 168c:003c, 5 GHz, 2x2, 26dBm
  - AR8035-A PHY	RGMII GbE with PoE+ IN
  - 40 MHz clock
  - 16 MB FLASH		MX25L12845EMI-10G
  - 2x 64 MB RAM	NT5TU32M16
  - UART console	J10, populated, RX shorted to ground
  - 4 antennas		5 dBi, internal omni-directional plates
  - 4 LEDs		power, 2G, 5G, wps
  - 1 button		reset

  NOTE: all 4 gpio controlled LEDS are viewed through the same lightguide
	therefore, the power LED is off for default state

**MAC addresses:**

  MAC address labeled as ETH
  Only one Vendor MAC address in flash at art 0x0

  eth0 ETH  *:e1 art 0x0
  phy1 2.4G *:e2 ---
  phy0 5GHz *:e3 ---

**Serial Access:**

  the RX line on the board for UART is shorted to ground by resistor R176
  therefore it must be removed to use the console
  but it is not necessary to remove to view boot log

  optionally, R175 can be replaced with a solder bridge short

  the resistors R175 and R176 are next to the UART RX pin at J10

**Installation:**

  Method 1: Firmware upgrade page:

    (if you cannot access the APs webpage)
    factory reset with the reset button
    connect ethernet to a computer
    OEM webpage at 192.168.20.253
    username and password 'araknis'
    make a new password, login again...

    Navigate to 'File Management' page from left pane
    Click Browse and select the factory.bin image
    Upload and verify checksum
    Click Continue to confirm
    wait about 3 minutes

  Method 2: Serial to load Failsafe webpage:

    After connecting to serial console and rebooting...
    Interrupt uboot with any key pressed rapidly
    execute `run failsafe_boot` OR `bootm 0x9fd70000`
    wait a minute
    connect to ethernet and navigate to
    192.168.20.253
    Select the factory.bin image and upload
    wait about 3 minutes

**Return to OEM:**

  Method 1: Serial to load Failsafe webpage (above)

  Method 2: delete a checksum from uboot-env
  this will make uboot load the failsafe image at next boot
  because it will fail the checksum verification of the image

    ssh into openwrt and run
    `fw_setenv rootfs_checksum 0`
    reboot, wait a minute
    connect to ethernet and navigate to
    192.168.20.253
    select OEM firmware image and click upgrade

  Method 3: backup mtd partitions before upgrade

**TFTP recovery:**

  Requires serial console, reset button does nothing

  rename initramfs-kernel.bin to '0101A8C0.img'
  make available on TFTP server at 192.168.1.101
  power board, interrupt boot with serial console
  execute `tftpboot` and `bootm 0x81000000`

  NOTE: TFTP may not be reliable due to bugged bootloader
	set MTU to 600 and try many times

**Format of OEM firmware image:**

  The OEM software is built using SDKs from Senao
  which is based on a heavily modified version
  of Openwrt Kamikaze or Altitude Adjustment.
  One of the many modifications is sysupgrade being performed by a custom script.
  Images are verified through successful unpackaging, correct filenames
  and size requirements for both kernel and rootfs files, and that they
  start with the correct magic numbers (first 2 bytes) for the respective headers.

  Newer Senao software requires more checks but their script
  includes a way to skip them.

  The OEM upgrade script is at
  /etc/fwupgrade.sh

  OKLI kernel loader is required because the OEM software
  expects the kernel to be less than 1536k
  and the OEM upgrade procedure would otherwise
  overwrite part of the kernel when writing rootfs.

Note on PLL-data cells:

  The default PLL register values will not work
  because of the external AR8035 switch between
  the SOC and the ethernet port.

  For QCA955x series, the PLL registers for eth0 and eth1
  can be see in the DTSI as 0x28 and 0x48 respectively.
  Therefore the PLL registers can be read from uboot
  for each link speed after attempting tftpboot
  or another network action using that link speed
  with `md 0x18050028 1` and `md 0x18050048 1`.

  The clock delay required for RGMII can be applied at the PHY side,
  using the at803x driver `phy-mode` setting through the DTS.
  Therefore, the Ethernet Configuration registers for GMAC0
  do not need the bits for RGMII delay on the MAC side.
  This is possible due to fixes in at803x driver
  since Linux 5.1 and 5.3

             connected to SoC UART through a SIPEX 3232EC for voltage
             level shifting.

* 'J5' RS232 Pinout (dot as pin 1):
  2) SoC RXD
  3) GND
  10) SoC TXD

Serial connection parameters: 115200 8N1.

Installation
------------

OEM upgrade method:

* Log in to OEM management web interface

* Navigate to Maintenance > Firmware > Management

* If "Active Image" has the first option selected, OpenWrt will need to be
  flashed to the "Active" partition. If the second option is selected,
  OpenWrt will need to be flashed to the "Backup" partition.

* Navigate to Maintenance > Firmware > Upload

* Upload the openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-initramfs-kernel.bin
  file by your preferred method to the previously determined partition.
  When prompted, select to boot from the newly flashed image, and reboot
  the switch.

* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:

  > sysupgrade /tmp/openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-squashfs-sysupgrade.bin

U-Boot TFTP method:

* Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10).

* Set up a TFTP server on your client and make it serve the initramfs
  image.

* Connect serial, power up the switch, interrupt U-boot by hitting the
  space bar, and enable the network:

  > rtk network on

> Since the GS1900-24 v1 is a dual-partition device, you want to keep the
  OEM firmware on the backup partition for the time being. OpenWrt can
  only be installed in the first partition anyway (hardcoded in the
  DTS). To ensure we are set to boot from the first partition, issue the
  following commands:

  > setsys bootpartition 0
  > savesys

* Download the image onto the device and boot from it:

  > tftpboot 0x81f00000 192.168.1.10:openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-initramfs-kernel.bin
  > bootm

* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:

  > sysupgrade /tmp/openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-squashfs-sysupgrade.bin

7ac8da0060 ath79: support ZTE MF286A/R
ZTE MF286A and MF286R are indoor LTE category 6/7 CPE router with simultaneous
dual-band 802.11ac plus 802.11n Wi-Fi radios and quad-port gigabit
Ethernet switch, FXS and external USB 2.0 port.

Hardware highlights:
- CPU: QCA9563 SoC at 775MHz,
- RAM: 128MB DDR2,
- NOR Flash: MX25L1606E 2MB SPI Flash, for U-boot only,
- NAND Flash: W25N01GV 128MB SPI NAND-Flash, for all other data,
- Wi-Fi 5GHz: QCA9886 2x2 MIMO 802.11ac Wave2 radio,
- WI-Fi 2.4GHz: QCA9563 3x3 MIMO 802.11n radio,
- Switch: QCA8337v2 4-port gigabit Ethernet, with single SGMII CPU port,
- WWAN:
  [MF286A] MDM9230-based category 6 internal LTE modem
  [MF286R] PXA1826-based category 7 internal LTE modem
  in extended  mini-PCIE form factor, with 3 internal antennas and
  2 external antenna connections, single mini-SIM slot.
- FXS: one external ATA port (handled entirely by modem part) with two
  physical connections in parallel,
- USB: Single external USB 2.0 port,
- Switches: power switch, WPS, Wi-Fi and reset buttons,
- LEDs: Wi-Fi, Test (internal). Rest of LEDs (Phone, WWAN, Battery,
  Signal state) handled entirely by modem. 4 link status LEDs handled by
  the switch on the backside.
- Battery: 3Ah 1-cell Li-Ion replaceable battery, with charging and
  monitoring handled by modem.
- Label MAC device: eth0

The device shares many components with previous model, MF286, differing
mostly by a Wave2 5GHz radio, flash layout and internal LED color.
In case of MF286A, the modem is the same as in MF286. MF286R uses a
different modem based on Marvell PXA1826 chip.

Internal modem of MF286A is supported via uqmi, MF286R modem isn't fully
supported, but it is expected to use comgt-ncm for connection, as it
uses standard 3GPP AT commands for connection establishment.

Console connection: connector X2 is the console port, with the following
pinout, starting from pin 1, which is the topmost pin when the board is
upright:
- VCC (3.3V). Do not use unless you need to source power for the
  converer from it.
- TX
- RX
- GND
Default port configuration in U-boot as well as in stock firmware is
115200-8-N-1.

Installation:
Due to different flash layout from stock firmware, sysupgrade from
within stock firmware is impossible, despite it's based on QSDK which
itself is based on OpenWrt.

STEP 0: Stock firmware update:
As installing OpenWrt cuts you off from official firmware updates for
the modem part, it is recommended to update the stock firmware to latest
version before installation, to have built-in modem at the latest firmware
version.

STEP 1: gaining root shell:

Method 1:
This works if busybox has telnetd compiled in the binary.
If this does not work, try method 2.

Using well-known exploit to start telnetd on your router - works
only if Busybox on stock firmware has telnetd included:
- Open stock firmware web interface
- Navigate to "URL filtering" section by going to "Advanced settings",
  then "Firewall" and finally "URL filter".
- Add an entry ending with "&&telnetd&&", for example
  "http://hostname/&&telnetd&&".
- telnetd will immediately listen on port 4719.
- After connecting to telnetd use "admin/admin" as credentials.

Method 2:
This works if busybox does not have telnetd compiled in. Notably, this
is the case in DNA.fi firmware.
If this does not work, try method 3.

- Set IP of your computer to 192.168.0.22. (or appropriate subnet if
  changed)
- Have a TFTP server running at that address
- Download MIPS build of busybox including telnetd, for example from:
  https://busybox.net/downloads/binaries/1.21.1/busybox-mips
  and put it in it's root directory. Rename it as "telnetd".
- As previously, login to router's web UI and navigate to "URL
  filtering"
- Using "Inspect" feature, extend "maxlength" property of the input
  field named "addURLFilter", so it looks like this:
  <input type="text" name="addURLFilter" id="addURLFilter" maxlength="332"
    class="required form-control">
- Stay on the page - do not navigate anywhere
- Enter "http://aa&zte_debug.sh 192.168.0.22 telnetd" as a filter.
- Save the settings. This will download the telnetd binary over tftp and
  execute it. You should be able to log in at port 23, using
  "admin/admin" as credentials.

Method 3:
If the above doesn't work, use the serial console - it exposes root shell
directly without need for login. Some stock firmwares, notably one from
finnish DNA operator lack telnetd in their builds.

STEP 2: Backing up original software:
As the stock firmware may be customized by the carrier and is not
officially available in the Internet, IT IS IMPERATIVE to back up the
stock firmware, if you ever plan to returning to stock firmware.
It is highly recommended to perform backup using both methods, to avoid
hassle of reassembling firmware images in future, if a restore is
needed.

Method 1: after booting OpenWrt initramfs image via TFTP:
PLEASE NOTE: YOU CANNOT DO THIS IF USING INTERMEDIATE FIRMWARE FOR INSTALLATION.
- Dump stock firmware located on stock kernel and ubi partitions:

  ssh root@192.168.1.1: cat /dev/mtd4 > mtd4_kernel.bin
  ssh root@192.168.1.1: cat /dev/mtd9 > mtd9_ubi.bin

And keep them in a safe place, should a restore be needed in future.

Method 2: using stock firmware:
- Connect an external USB drive formatted with FAT or ext4 to the USB
  port.
- The drive will be auto-mounted to /var/usb_disk
- Check the flash layout of the device:

  cat /proc/mtd

  It should show the following:
  mtd0: 000a0000 00010000 "u-boot"
  mtd1: 00020000 00010000 "u-boot-env"
  mtd2: 00140000 00010000 "reserved1"
  mtd3: 000a0000 00020000 "fota-flag"
  mtd4: 00080000 00020000 "art"
  mtd5: 00080000 00020000 "mac"
  mtd6: 000c0000 00020000 "reserved2"
  mtd7: 00400000 00020000 "cfg-param"
  mtd8: 00400000 00020000 "log"
  mtd9: 000a0000 00020000 "oops"
  mtd10: 00500000 00020000 "reserved3"
  mtd11: 00800000 00020000 "web"
  mtd12: 00300000 00020000 "kernel"
  mtd13: 01a00000 00020000 "rootfs"
  mtd14: 01900000 00020000 "data"
  mtd15: 03200000 00020000 "fota"
  mtd16: 01d00000 00020000 "firmware"

  Differences might indicate that this is NOT a MF286A device but
  one of other variants.
- Copy over all MTD partitions, for example by executing the following:

  for i in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15; do cat /dev/mtd$i > \
  /var/usb_disk/mtd$i; done

  "Firmware" partition can be skipped, it is a concatenation
  of "kernel" and "rootfs".

- If the count of MTD partitions is different, this might indicate that
  this is not a MF286A device, but one of its other variants.
- (optionally) rename the files according to MTD partition names from
  /proc/mtd
- Unmount the filesystem:

  umount /var/usb_disk; sync

  and then remove the drive.
- Store the files in safe place if you ever plan to return to stock
  firmware. This is especially important, because stock firmware for
  this device is not available officially, and is usually customized by
  the mobile providers.

STEP 3: Booting initramfs image:

Method 1: using serial console (RECOMMENDED):
- Have TFTP server running, exposing the OpenWrt initramfs image, and
  set your computer's IP address as 192.168.0.22. This is the default
  expected by U-boot. You may wish to change that, and alter later
  commands accordingly.
- Connect the serial console if you haven't done so already,
- Interrupt boot sequence by pressing any key in U-boot when prompted
- Use the following commands to boot OpenWrt initramfs through TFTP:

  setenv serverip 192.168.0.22
  setenv ipaddr 192.168.0.1
  tftpboot 0x81000000 openwrt-ath79-nand-zte_mf286a-initramfs-kernel.bin
  bootm 0x81000000

  (Replace server IP and router IP as needed). There is no  emergency
  TFTP boot sequence triggered by buttons, contrary to MF283+.
- When OpenWrt initramfs finishes booting, proceed to actual
  installation.

Method 2: using initramfs image as temporary boot kernel
This exploits the fact, that kernel and rootfs MTD devices are
consecutive on NAND flash, so from within stock image, an initramfs can
be written to this area and booted by U-boot on next reboot, because it
uses "nboot" command which isn't limited by kernel partition size.
- Download the initramfs-kernel.bin image
- After backing up the previous MTD contents, write the images to the
  "firmware" MTD device, which conveniently concatenates "kernel" and
  "rootfs" partitions that can fit the initramfs image:

  nandwrite -p /dev/<firmware-mtd> \
  /var/usb_disk/openwrt-ath79-zte_mf286a-initramfs-kernel.bin

- If write is OK, reboot the device, it will reboot to OpenWrt
  initramfs:

  reboot -f

- After rebooting, SSH into the device and use sysupgrade to perform
  proper installation.

Method 3: using built-in TFTP recovery (LAST RESORT):
- With that method, ensure you have complete backup of system's NAND
  flash first. It involves deliberately erasing the kernel.
- Download "-initramfs-kernel.bin" image for the device.
- Prepare the recovery image by prepending 8MB of zeroes to the image,
  and name it root_uImage:

  dd if=/dev/zero of=padding.bin bs=8M count=1

  cat padding.bin openwrt-ath79-nand-zte_mf286a-initramfs-kernel.bin >
  root_uImage

- Set up a TFTP server at 192.0.0.1/8. Router will use random address
  from that range.
- Put the previously generated "root_uImage" into TFTP server root
  directory.
- Deliberately erase "kernel" partition" using stock firmware after
  taking backup. THIS IS POINT OF NO RETURN.
- Restart the device. U-boot will attempt flashing the recovery
  initramfs image, which will let you perform actual installation using
  sysupgrade. This might take a considerable time, sometimes the router
  doesn't establish Ethernet link properly right after booting. Be
  patient.
- After U-boot finishes flashing, the LEDs of switch ports will all
  light up. At this moment, perform power-on reset, and wait for OpenWrt
  initramfs to finish booting. Then proceed to actual installation.

STEP 4: Actual installation:
- Set your computer IP to 192.168.1.22/24
- scp the sysupgrade image to the device:

  scp openwrt-ath79-nand-zte_mf286a-squashfs-sysupgrade.bin \
  root@192.168.1.1:/tmp/

- ssh into the device and execute sysupgrade:

  sysupgrade -n /tmp/openwrt-ath79-nand-zte_mf286a-squashfs-sysupgrade.bin

- Wait for router to reboot to full OpenWrt.

STEP 5: WAN connection establishment
Since the router is equipped with LTE modem as its main WAN interface, it
might be useful to connect to the Internet right away after
installation. To do so, please put the following entries in
/etc/config/network, replacing the specific configuration entries with
one needed for your ISP:

config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option auth '<auth>' # As required, usually 'none'
        option pincode '<pin>' # If required by SIM
        option apn '<apn>' # As required by ISP
        option pdptype '<pdp>' # Typically 'ipv4', or 'ipv4v6' or 'ipv6'

For example, the following works for most polish ISPs
config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option auth 'none'
        option apn 'internet'
        option pdptype 'ipv4'

The required minimum is:
config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
In this case, the modem will use last configured APN from stock
firmware - this should work out of the box, unless your SIM requires
PIN which can't be switched off.

If you have build with LuCI, installing luci-proto-qmi helps with this
task.

Restoring the stock firmware:

Preparation:
If you took your backup using stock firmware, you will need to
reassemble the partitions into images to be restored onto the flash. The
layout might differ from ISP to ISP, this example is based on generic stock
firmware
The only partitions you really care about are "web", "kernel", and
"rootfs". These are required to restore the stock firmware through
factory TFTP recovery.

Because kernel partition was enlarged, compared to stock
firmware, the kernel and rootfs MTDs don't align anymore, and you need
to carve out required data if you only have backup from stock FW:
- Prepare kernel image
  cat mtd12_kernel.bin mtd13_rootfs.bin > owrt_kernel.bin
  truncate -s 4M owrt_kernel_restore.bin
- Cut off first 1MB from rootfs
  dd if=mtd13_rootfs.bin of=owrt_rootfs.bin bs=1M skip=1
- Prepare image to write to "ubi" meta-partition:
  cat mtd6_reserved2.bi mtd7_cfg-param.bin mtd8_log.bin mtd9_oops.bin \
  mtd10_reserved3.bin mtd11_web.bin owrt_rootfs.bin > \
  owrt_ubi_ubi_restore.bin

You can skip the "fota" partition altogether,
it is used only for stock firmware update purposes and can be overwritten
safely anyway. The same is true for "data" partition which on my device
was found to be unused at all. Restoring mtd5_cfg-param.bin will restore
the stock firmware configuration you had before.

Method 1: Using initramfs:
This method is recmmended if you took your backup from within OpenWrt
initramfs, as the reassembly is not needed.
- Boot to initramfs as in step 3:
- Completely detach ubi0 partition using ubidetach /dev/ubi0_0
- Look up the kernel and ubi partitions in /proc/mtd
- Copy over the stock kernel image using scp to /tmp
- Erase kernel and restore stock kernel:
  (scp mtd4_kernel.bin root@192.168.1.1:/tmp/)
  mtd write <kernel_mtd> mtd4_kernel.bin
  rm mtd4_kernel.bin
- Copy over the stock partition backups one-by-one using scp to /tmp, and
  restore them individually. Otherwise you might run out of space in
  tmpfs:

  (scp mtd3_ubiconcat0.bin root@192.168.1.1:/tmp/)

  mtd write <ubiconcat0_mtd> mtd3_ubiconcat0.bin
  rm mtd3_ubiconcat0.bin

  (scp mtd5_ubiconcat1.bin root@192.168.1.1:/tmp/)

  mtd write <ubiconcat1_mtd> mtd5_ubiconcat1.bin
  rm mtd5_ubiconcat1.bin

- If the write was correct, force a device reboot with

  reboot -f

Method 2: Using live OpenWrt system (NOT RECOMMENDED):
- Prepare a USB flash drive contatining MTD backup files
- Ensure you have kmod-usb-storage and filesystem driver installed for
  your drive
- Mount your flash drive

  mkdir /tmp/usb

  mount /dev/sda1 /tmp/usb

- Remount your UBI volume at /overlay to R/O

  mount -o remount,ro /overlay

- Write back the kernel and ubi partitions from USB drive

  cd /tmp/usb
  mtd write mtd4_kernel.bin /dev/<kernel_mtd>

  mtd write mtd9_ubi.bin /dev/<kernel_ubi>

- If everything went well, force a device reboot with
  reboot -f

Last image may be truncated a bit due to lack of space in RAM, but this will happen over "fota"
MTD partition which may be safely erased after reboot anyway.

Method 3: using built-in TFTP recovery:
This method is recommended if you took backups using stock firmware.
- Assemble a recovery rootfs image from backup of stock partitions by
  concatenating "web", "kernel", "rootfs" images dumped from the device,
  as "root_uImage"
- Use it in place of "root_uImage" recovery initramfs image as in the
  TFTP pre-installation method.

Quirks and known issuesa
- It was observed, that CH340-based USB-UART converters output garbage
  during U-boot phase of system boot. At least CP2102 is known to work
  properly.
- Kernel partition size is increased to 4MB compared to stock 3MB, to
  accomodate future kernel updates - at this moment OpenWrt 5.10 kernel
  image is at 2.5MB which is dangerously close to the limit. This has no
  effect on booting the system - but keep that in mind when reassembling
  an image to restore stock firmware.
- uqmi seems to be unable to change APN manually, so please use the one
  you used before in stock firmware first. If you need to change it,
  please use protocok '3g' to establish connection once, or use the
  following command to change APN (and optionally IP type) manually:
  echo -ne 'AT+CGDCONT=1,"IP","<apn>' > /dev/ttyUSB0
- The only usable LED as a "system LED" is the blue debug LED hidden
  inside the case. All other LEDs are controlled by modem, on which the
  router part has some influence only on Wi-Fi LED.
- Wi-Fi LED currently doesn't work while under OpenWrt, despite having
  correct GPIO mapping. All other LEDs are controlled by modem,
  including this one in stock firmware. GPIO19, mapped there only acts
  as a gate, while the actual signal source seems to be 5GHz Wi-Fi
  radio, however it seems it is not the LED exposed by ath10k as
  ath10k-phy0.
- GPIO5 used for modem reset is a suicide switch, causing a hardware
  reset of whole board, not only the modem. It is attached to
  gpio-restart driver, to restart the modem on reboot as well, to ensure
  QMI connectivity after reboot, which tends to fail otherwise.
- Modem, as in MF283+, exposes root shell over ADB - while not needed
  for OpenWrt operation at all - have fun lurking around.
  The same modem module is used as in older MF286.

1050e66c8f x86: grub2: search for the "kernel" filesystem on all disks
Previously, grub2 was hardcoded to always look on "hd0" for the
kernel.

This works well when the system only had a single disk.
But if there was a second disk/stick present, it may have look
on the wrong drive because of enumeration races.

This patch utilizes grub2 search function to look for a filesystem
with the label "kernel". This works thanks to existing setup in
scripts/gen_image_generic.sh. Which sets the "kernel" label on
both the fat and ext4 filesystem variants.

cfe79f2eb8 mpc85xx: Patch HiveAP 330 u-boot to fix boot
When Kernel 5.10 was enabled for mpc85xx, the kernel once again became too
large upon decompression (>7MB or so) to decompress itself on boot (see
FS#4110[1]).

There have been many attempts to fix booting from a compressed kernel on
the HiveAP-330:

- b683f1c36d ("mpc85xx: Use gzip compressed kernel on HiveAP-330")
- 98089bb8ba ("mpc85xx: Use uncompressed kernel on the HiveAP-330")
- 26cb167a5c ("mpc85xx: Fix Aerohive HiveAP-330 initramfs image")

We can no longer compress the kernel due to size, and the stock bootloader
does not support any other types of compression. Since an uncompressed
kernel no longer fits in the 8MiB kernel partition at 0x2840000, we need to
patch u-boot to autoboot by running variable which isn't set by the
bootloader on each autoboot.

This commit repartitions the HiveAP, requiring a new COMPAT_VERSION,
and uses the DEVICE_COMPAT_MESSAGE to guide the user to patch u-boot,
which changes the variable run on boot to be `owrt_boot`; the user can
then set the value of that variable appropriately.

The following has been documented in the device's OpenWrt wiki page:
<https://openwrt.org/toh/aerohive/hiveap-330>. Please look there
first/too for more information.

The from-stock and upgrade from a previous installation now becomes:

0) setup a network with a dhcp server and a tftp server at serverip
(192.168.1.101) with the initramfs image in the servers root directory.

1) Hook into UART (9600 baud) and enter U-Boot. You may need to enter
a password of administrator or AhNf?d@ta06 if prompted. If the password
doesn't work. Try reseting the device by pressing and holding the reset
button with the stock OS.

2) Once in U-Boot, set the new owrt_boot and tftp+boot the initramfs image:
   Use copy and paste!

 # fw_setenv owrt_boot 'setenv bootargs \"console=ttyS0,$baudrate\";bootm 0xEC040000 - 0xEC000000'
 # save
 # dhcp
 # setenv bootargs console=ttyS0,$baudrate
 # tftpboot 0x1000000 192.168.1.101:openwrt-mpc85xx-p1020-aerohive_hiveap-330-initramfs-kernel.bin
 # bootm

3) Once openwrt booted:
carefully copy and paste this into the root shell. One step at a time

  # 3.0 install kmod-mtd-rw from the internet and load it

  opkg update; opkg install kmod-mtd-rw
  insmod mtd-rw i_want_a_brick=y

  # 3.1 create scripts that modifies uboot

cat <<- "EOF" > /tmp/uboot-update.sh
  . /lib/functions/system.sh
  cp "/dev/mtd$(find_mtd_index 'u-boot')" /tmp/uboot
  cp /tmp/uboot /tmp/uboot_patched
  ofs=$(strings -n80 -td < /tmp/uboot | grep '^ [0-9]* setenv bootargs.*cp\.l' | cut -f2 -d' ')
  for off in $ofs; do
    printf "run owrt_boot;            " | dd of=/tmp/uboot_patched bs=1 seek=${off} conv=notrunc
  done
  md5sum /tmp/uboot*
EOF

  # 3.2 run the script to do the modification

  sh /tmp/uboot-update.sh

  # verify that /tmp/uboot and /tmp/uboot_patched are good
  #
  # my uboot was: (is printed during boot)
  # U-Boot 2009.11 (Jan 12 2017 - 00:27:25), Build: jenkins-HiveOS-Honolulu_AP350_Rel-245
  #
  # d84b45a2e8aca60d630fbd422efc6b39  /tmp/uboot
  # 6dc420f24c2028b9cf7f0c62c0c7f692  /tmp/uboot_patched
  # 98ebc7e7480ce9148cd2799357a844b0  /tmp/uboot-update.sh <-- just for reference

  # 3.3 this produces the /tmp/u-boot_patched file.

  mtd write /tmp/uboot_patched u-boot

3) scp over the sysupgrade file to /tmp/ and run sysupgrade to flash OpenWrt:

  sysupgrade -n /tmp/openwrt-mpc85xx-p1020-aerohive_hiveap-330-squashfs-sysupgrade.bin

4) after the reboot, you are good to go.

Other notes:

- Note that after this sysupgrade, the AP will be unavailable for 7 minutes
  to reformat flash. The tri-color LED does not blink in any way to
  indicate this, though there is no risk in interrupting this process,
  other than the jffs2 reformat being reset.

- Add a uci-default to fix the compat version. This will prevent updates
  from previous versions without going through the installation process.

- Enable CONFIG_MTD_SPLIT_UIMAGE_FW and adjust partitioning to combine
  the kernel and rootfs into a single dts partition to maximize storage
  space, though in practice the kernel can grow no larger than 16MiB due
  to constraints of the older mpc85xx u-boot platform.

- Because of that limit, KERNEL_SIZE has been raised to 16m.

- A .tar.gz of the u-boot source for the AP330 (a.k.a. Goldengate) can
  be found here[2].

- The stock-jffs2 partition is also removed to make more space -- this
  is possible only now that it is no longer split away from the rootfs.

- the console-override is gone. The device will now get the console
  through the bootargs. This has the advantage that you can set a different
  baudrate in uboot and the linux kernel will stick with it!

- due to the repartitioning, the partition layout and names got a makeover.

- the initramfs+fdt method is now combined into a MultiImage initramfs.
  The separate fdt download is no longer needed.

- added uboot-envtools to the mpc85xx target. All targets have uboot and
  this way its available in the initramfs.

      1.2.4. Set wireless network interface's IP to 169.254.31.1, turn
             off DHCP of wireless interface's zone.
      1.2.5. Connect to the router wirelessly, manually set your access
             device's IP to 169.254.31.3, make sure
             http://169.254.31.1/cgi-bin/luci/api/xqsystem/token
             still have a similar result as 1.2.3 shows.
   1.3. On the Xiaomi CR660x:
        1.3.1. Login to the web interface. Your would be directed to a
               page with URL like this:
               http://{ROUTER_ADDR}/cgi-bin/luci/;stok={STOK}/web/home#r-
               outer
        1.3.2. Browse this URL with {STOK} from 1.3.1, {WIFI_NAME}
               {PASSWORD} be your OpenWrt router's SSID and password:
               http://{MIROUTER_ADDR}/cgi-bin/luci/;stok={STOK}/api/misy-
               stem/extendwifi_connect?ssid={WIFI_NAME}&password={PASSWO-
               RD}
               It should return 0.
        1.3.3. Browse this URL with {STOK} from 1.3.1:
               http://{MIROUTER_ADDR}/cgi-bin/luci/;stok={STOK}/api/xqsy-
               stem/oneclick_get_remote_token?username=xxx&password=xxx&-
               nonce=xxx
   1.4. Before rebooting, you can now access your CR660x via SSH.
        For CR6606, you can calculate your root password by this project:
        https://github.com/wfjsw/xiaoqiang-root-password, or at
        https://www.oxygen7.cn/miwifi.
        The root password for carrier-specific models should be the admi-
        nistration password or the default login password on the label.
        It is also feasible to change the root password at the same time
        by modifying the script from step 1.2.2.
        You can treat OpenWrt Router however you like from this point as
        long as you don't mind go through this again if you have to expl-
        oit it again. If you do have to and left your OpenWrt router unt-
        ouched, start from 1.3.
2. There's no official binary firmware available, and if you lose the
   content of your flash, no one except Xiaomi can help you.
   Dump these partitions in case you need them:
   "Bootloader" "Nvram" "Bdata" "crash" "crash_log"
   "firmware" "firmware1" "overlay" "obr"
   Find the corespond block device from /proc/mtd
   Read from read-only block device to avoid misoperation.
   It's recommended to use /tmp/syslogbackup/ as destination, since files
   would be available at http://{ROUTER_ADDR}/backup/log/YOUR_DUMP
   Keep an eye on memory usage though.
3. Since UART access is locked ootb, you should get UART access by modify
   uboot env. Otherwise, your router may become bricked.
   Excute these in stock firmware shell:
    a. nvram set boot_wait=on
    b. nvram set bootdelay=3
    c. nvram commit
   Or in OpenWrt:
    a. opkg update && opkg install kmod-mtd-rw
    b. insmod mtd-rw i_want_a_brick=1
    c. fw_setenv boot_wait on
    d. fw_setenv bootdelay 3
    e. rmmod mtd-rw

Migrate to OpenWrt:
 1. Transfer squashfs-firmware.bin to the router.
 2. nvram set flag_try_sys1_failed=0
 3. nvram set flag_try_sys2_failed=1
 4. nvram commit
 5. mtd -r write /path/to/image/squashfs-firmware.bin firmware

Additional Info:
 1. CR660x series routers has a different nand layout compared to other
    Xiaomi nand devices.
 2. This router has a relatively fresh uboot (2018.09) compared to other
    Xiaomi devices, and it is capable of booting fit image firmware.
    Unfortunately, no successful attempt of booting OpenWrt fit image
    were made so far. The cause is still yet to be known. For now, we use
    legacy image instead.

- TX
- RX
- GND
Default port configuration in U-boot as well as in stock firmware is
115200-8-N-1.

Installation:
Due to different flash layout from stock firmware, sysupgrade from
within stock firmware is impossible, despite it's based on QSDK which
itself is based on OpenWrt.

STEP 0: Stock firmware update:
As installing OpenWrt cuts you off from official firmware updates for
the modem part, it is recommended to update the stock firmware to latest
version before installation, to have built-in modem at the latest firmware
version.

STEP 1: gaining root shell:

Method 1:
This works if busybox has telnetd compiled in the binary.
If this does not work, try method 2.

Using well-known exploit to start telnetd on your router - works
only if Busybox on stock firmware has telnetd included:
- Open stock firmware web interface
- Navigate to "URL filtering" section by going to "Advanced settings",
  then "Firewall" and finally "URL filter".
- Add an entry ending with "&&telnetd&&", for example
  "http://hostname/&&telnetd&&".
- telnetd will immediately listen on port 4719.
- After connecting to telnetd use "admin/admin" as credentials.

Method 2:
This works if busybox does not have telnetd compiled in. Notably, this
is the case in DNA.fi firmware.
If this does not work, try method 3.

- Set IP of your computer to 192.168.1.22.
- Have a TFTP server running at that address
- Download MIPS build of busybox including telnetd, for example from:
  https://busybox.net/downloads/binaries/1.21.1/busybox-mips
  and put it in it's root directory. Rename it as "telnetd".
- As previously, login to router's web UI and navigate to "URL
  filtering"
- Using "Inspect" feature, extend "maxlength" property of the input
  field named "addURLFilter", so it looks like this:
  <input type="text" name="addURLFilter" id="addURLFilter" maxlength="332"
    class="required form-control">
- Stay on the page - do not navigate anywhere
- Enter "http://aa&zte_debug.sh 192.168.1.22 telnetd" as a filter.
- Save the settings. This will download the telnetd binary over tftp and
  execute it. You should be able to log in at port 23, using
  "admin/admin" as credentials.

Method 3:
If the above doesn't work, use the serial console - it exposes root shell
directly without need for login. Some stock firmwares, notably one from
finnish DNA operator lack telnetd in their builds.

STEP 2: Backing up original software:
As the stock firmware may be customized by the carrier and is not
officially available in the Internet, IT IS IMPERATIVE to back up the
stock firmware, if you ever plan to returning to stock firmware.

Method 1: after booting OpenWrt initramfs image via TFTP:
PLEASE NOTE: YOU CANNOT DO THIS IF USING INTERMEDIATE FIRMWARE FOR INSTALLATION.
- Dump stock firmware located on stock kernel and ubi partitions:

  ssh root@192.168.1.1: cat /dev/mtd4 > mtd4_kernel.bin
  ssh root@192.168.1.1: cat /dev/mtd8 > mtd8_ubi.bin

And keep them in a safe place, should a restore be needed in future.

Method 2: using stock firmware:
- Connect an external USB drive formatted with FAT or ext4 to the USB
  port.
- The drive will be auto-mounted to /var/usb_disk
- Check the flash layout of the device:

  cat /proc/mtd

  It should show the following:
  mtd0: 00080000 00010000 "uboot"
  mtd1: 00020000 00010000 "uboot-env"
  mtd2: 00140000 00020000 "fota-flag"
  mtd3: 00140000 00020000 "caldata"
  mtd4: 00140000 00020000 "mac"
  mtd5: 00600000 00020000 "cfg-param"
  mtd6: 00140000 00020000 "oops"
  mtd7: 00800000 00020000 "web"
  mtd8: 00300000 00020000 "kernel"
  mtd9: 01f00000 00020000 "rootfs"
  mtd10: 01900000 00020000 "data"
  mtd11: 03200000 00020000 "fota"

  Differences might indicate that this is NOT a vanilla MF286 device but
  one of its later derivatives.
- Copy over all MTD partitions, for example by executing the following:

  for i in 0 1 2 3 4 5 6 7 8 9 10 11; do cat /dev/mtd$i > \
  /var/usb_disk/mtd$i; done

- If the count of MTD partitions is different, this might indicate that
  this is not a standard MF286 device, but one of its later derivatives.
- (optionally) rename the files according to MTD partition names from
  /proc/mtd
- Unmount the filesystem:

  umount /var/usb_disk; sync

  and then remove the drive.
- Store the files in safe place if you ever plan to return to stock
  firmware. This is especially important, because stock firmware for
  this device is not available officially, and is usually customized by
  the mobile providers.

STEP 3: Booting initramfs image:

Method 1: using serial console (RECOMMENDED):
- Have TFTP server running, exposing the OpenWrt initramfs image, and
  set your computer's IP address as 192.168.1.22. This is the default
  expected by U-boot. You may wish to change that, and alter later
  commands accordingly.
- Connect the serial console if you haven't done so already,
- Interrupt boot sequence by pressing any key in U-boot when prompted
- Use the following commands to boot OpenWrt initramfs through TFTP:

  setenv serverip 192.168.1.22
  setenv ipaddr 192.168.1.1
  tftpboot 0x81000000 openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin
  bootm 0x81000000

  (Replace server IP and router IP as needed). There is no  emergency
  TFTP boot sequence triggered by buttons, contrary to MF283+.
- When OpenWrt initramfs finishes booting, proceed to actual
  installation.

Method 2: using initramfs image as temporary boot kernel
This exploits the fact, that kernel and rootfs MTD devices are
consecutive on NAND flash, so from within stock image, an initramfs can
be written to this area and booted by U-boot on next reboot, because it
uses "nboot" command which isn't limited by kernel partition size.
- Download the initramfs-kernel.bin image
- Split the image into two parts on 3MB partition size boundary, which
  is the size of kernel partition. Pad the output of second file to
  eraseblock size:

  dd if=openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin \
  bs=128k count=24 \
  of=openwrt-ath79-zte_mf286-intermediate-kernel.bin

  dd if=openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin \
  bs=128k skip=24 conv=sync \
  of=openwrt-ath79-zte_mf286-intermediate-rootfs.bin

- Copy over /usr/bin/flash_eraseall and /usr/bin/nandwrite utilities to
  /tmp. This is CRITICAL for installation, as erasing rootfs will cut
  you off from those tools on flash!

- After backing up the previous MTD contents, write the images to the
  respective MTD devices:

  /tmp/flash_eraseall /dev/<kernel-mtd>

  /tmp/nandwrite /dev/<kernel-mtd> \
  /var/usb_disk/openwrt-ath79-zte_mf286-intermediate-kernel.bin

  /tmp/flash_eraseall /dev/<kernel-mtd>

  /tmp/nandwrite /dev/<rootfs-mtd> \
  /var/usb_disk/openwrt-ath79-zte_mf286-intermediate-rootfs.bin

- Ensure that no bad blocks were present on the devices while writing.
  If they were present, you may need to vary the split  between
  kernel and rootfs parts, so U-boot reads a valid uImage after skipping
  the bad blocks. If it fails, you will be left with method 3 (below).
- If write is OK, reboot the device, it will reboot to OpenWrt
  initramfs:

  reboot -f

- After rebooting, SSH into the device and use sysupgrade to perform
  proper installation.

Method 3: using built-in TFTP recovery (LAST RESORT):
- With that method, ensure you have complete backup of system's NAND
  flash first. It involves deliberately erasing the kernel.
- Download "-initramfs-kernel.bin" image for the device.
- Prepare the recovery image by prepending 8MB of zeroes to the image,
  and name it root_uImage:

  dd if=/dev/zero of=padding.bin bs=8M count=1

  cat padding.bin openwrt-ath79-nand-zte_mf286-initramfs-kernel.bin >
  root_uImage

- Set up a TFTP server at 192.0.0.1/8. Router will use random address
  from that range.
- Put the previously generated "root_uImage" into TFTP server root
  directory.
- Deliberately erase "kernel" partition" using stock firmware after
  taking backup. THIS IS POINT OF NO RETURN.
- Restart the device. U-boot will attempt flashing the recovery
  initramfs image, which will let you perform actual installation using
  sysupgrade. This might take a considerable time, sometimes the router
  doesn't establish Ethernet link properly right after booting. Be
  patient.
- After U-boot finishes flashing, the LEDs of switch ports will all
  light up. At this moment, perform power-on reset, and wait for OpenWrt
  initramfs to finish booting. Then proceed to actual installation.

STEP 4: Actual installation:
- scp the sysupgrade image to the device:

  scp openwrt-ath79-nand-zte_mf286-squashfs-sysupgrade.bin \
  root@192.168.1.1:/tmp/

- ssh into the device and execute sysupgrade:

  sysupgrade -n /tmp/openwrt-ath79-nand-zte_mf286-squashfs-sysupgrade.bin

- Wait for router to reboot to full OpenWrt.

STEP 5: WAN connection establishment
Since the router is equipped with LTE modem as its main WAN interface, it
might be useful to connect to the Internet right away after
installation. To do so, please put the following entries in
/etc/config/network, replacing the specific configuration entries with
one needed for your ISP:

config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option auth '<auth>' # As required, usually 'none'
        option pincode '<pin>' # If required by SIM
        option apn '<apn>' # As required by ISP
        option pdptype '<pdp>' # Typically 'ipv4', or 'ipv4v6' or 'ipv6'

For example, the following works for most polish ISPs
config interface 'wan'
        option proto 'qmi'
        option device '/dev/cdc-wdm0'
        option auth 'none'
        option apn 'internet'
        option pdptype 'ipv4'

If you have build with LuCI, installing luci-proto-qmi helps with this
task.

Restoring the stock firmware:

Preparation:
If you took your backup using stock firmware, you will need to
reassemble the partitions into images to be restored onto the flash. The
layout might differ from ISP to ISP, this example is based on generic stock
firmware.
The only partitions you really care about are "web", "kernel", and
"rootfs". For easy padding and possibly restoring configuration, you can
concatenate most of them into images written into "ubi" meta-partition
in OpenWrt. To do so, execute something like:

cat mtd5_cfg-param.bin mtd6-oops.bin mtd7-web.bin mtd9-rootfs.bin > \
mtd8-ubi_restore.bin

You can skip the "fota" partition altogether,
it is used only for stock firmware update purposes and can be overwritten
safely anyway. The same is true for "data" partition which on my device
was found to be unused at all. Restoring mtd5_cfg-param.bin will restore
the stock firmware configuration you had before.

Method 1: Using initramfs:
- Boot to initramfs as in step 3:
- Completely detach ubi0 partition using ubidetach /dev/ubi0_0
- Look up the kernel and ubi partitions in /proc/mtd
- Copy over the stock kernel image using scp to /tmp
- Erase kernel and restore stock kernel:
  (scp mtd4_kernel.bin root@192.168.1.1:/tmp/)
  mtd write <kernel_mtd> mtd4_kernel.bin
  rm mtd4_kernel.bin
- Copy over the stock partition backups one-by-one using scp to /tmp, and
  restore them individually. Otherwise you might run out of space in
  tmpfs:

  (scp mtd3_ubiconcat0.bin root@192.168.1.1:/tmp/)

  mtd write <ubiconcat0_mtd> mtd3_ubiconcat0.bin
  rm mtd3_ubiconcat0.bin

  (scp mtd5_ubiconcat1.bin root@192.168.1.1:/tmp/)

  mtd write <ubiconcat1_mtd> mtd5_ubiconcat1.bin
  rm mtd5_ubiconcat1.bin

- If the write was correct, force a device reboot with

  reboot -f

Method 2: Using live OpenWrt system (NOT RECOMMENDED):
- Prepare a USB flash drive contatining MTD backup files
- Ensure you have kmod-usb-storage and filesystem driver installed for
  your drive
- Mount your flash drive

  mkdir /tmp/usb

  mount /dev/sda1 /tmp/usb

- Remount your UBI volume at /overlay to R/O

  mount -o remount,ro /overlay

- Write back the kernel and ubi partitions from USB drive

  cd /tmp/usb
  mtd write mtd4_kernel.bin /dev/<kernel_mtd>

  mtd write mtd8_ubi.bin /dev/<kernel_ubi>

- If everything went well, force a device reboot with
  reboot -f

Last image may be truncated a bit due to lack of space in RAM, but this will happen over "fota"
MTD partition which may be safely erased after reboot anyway.

Method 3: using built-in TFTP recovery (LAST RESORT):
- Assemble a recovery rootfs image from backup of stock partitions by
  concatenating "web", "kernel", "rootfs" images dumped from the device,
  as "root_uImage"
- Use it in place of "root_uImage" recovery initramfs image as in the
  TFTP pre-installation method.

Quirks and known issues
- Kernel partition size is increased to 4MB compared to stock 3MB, to
  accomodate future kernel updates - at this moment OpenWrt 5.10 kernel
  image is at 2.5MB which is dangerously close to the limit. This has no
  effect on booting the system - but keep that in mind when reassembling
  an image to restore stock firmware.
- uqmi seems to be unable to change APN manually, so please use the one
  you used before in stock firmware first. If you need to change it,
  please use protocok '3g' to establish connection once, or use the
  following command to change APN (and optionally IP type) manually:
  echo -ne 'AT+CGDCONT=1,"IP","<apn>' > /dev/ttyUSB0
- The only usable LED as a "system LED" is the green debug LED hidden
  inside the case. All other LEDs are controlled by modem, on which the
  router part has some influence only on Wi-Fi LED.
- Wi-Fi LED currently doesn't work while under OpenWrt, despite having
  correct GPIO mapping. All other LEDs are controlled by modem,
  including this one in stock firmware. GPIO19, mapped there only acts
  as a gate, while the actual signal source seems to be 5GHz Wi-Fi
  radio, however it seems it is not the LED exposed by ath10k as
  ath10k-phy0.
- GPIO5 used for modem reset is a suicide switch, causing a hardware
  reset of whole board, not only the modem. It is attached to
  gpio-restart driver, to restart the modem on reboot as well, to ensure
  QMI connectivity after reboot, which tends to fail otherwise.
- Modem, as in MF283+, exposes root shell over ADB - while not needed
  for OpenWrt operation at all - have fun lurking around.
- MAC address shift for 5GHz Wi-Fi used in stock firmware is
  0x320000000000, which is impossible to encode in the device tree, so I
  took the liberty of using MAC address increment of 1 for it, to ensure
  different BSSID for both Wi-Fi interfaces.
