a3d8c1295e ramips: Add support for SERCOMM NA502
The SERCOMM NA502 is a smart home gateway manufactured by SERCOMM and sold
under different brands (among others, A1 Telekom Austria SmartHome
Gateway). It has multi-protocol radio support in addition to LAN and WiFi.

Note: BLE is currently unsupported.

Specifications
--------------

  - MT7621ST 880MHz, Single-Core, Dual-Thread
  - MT7603EN 2.4GHz WiFi
  - MT7662EN 5GHz WiFi + BLE
  - 128MiB NAND
  - 256MiB DDR3 RAM
  - SD3503 ZWave Controller
  - EM357 Zigbee Coordinator

MAC address assignment
----------------------

LAN MAC is read from the config partition, WiFi 2.4GHz is LAN+2 and matches
the OEM firmware. WiFi 5GHz with LAN+1 is an educated guess since the
OEM firmware does not enable 5GHz WiFi.

Installation
------------
Attach serial console, then boot the initramfs image via TFTP.
Once inside OpenWrt, run sysupgrade -n with the sysupgrade file.

Attention: The device has a dual-firmware design. We overwrite kernel2,
since kernel1 contains an automatic recovery image.

If you get NAND ECC errors and are stuck with bad eraseblocks, try to
erase the mtd partition first with

mtd unlock ubi
mtd erase ubi

This should only be needed once.

b232680f84 ramips: add support for Linksys EA8100 v1
Specifications:
- SoC: MT7621AT
- RAM: 256MB
- Flash: 128MB NAND
- Ethernet: 5 Gigabit ports
- WiFi: 2.4G/5G MT7615N
- USB: 1 USB 3.0, 1 USB 2.0

This device is very similar to the EA7300 v1/v2 and EA7500 v2.

Installation:

Upload the generated factory image through the factory web interface.

(following part taken from EA7300 v2 commit message:)

This might fail due to the A/B nature of this device. When flashing, OEM
firmware writes over the non-booted partition. If booted from 'A',
flashing over 'B' won't work. To get around this, you should flash the
OEM image over itself. This will then boot the router from 'B' and
allow you to flash OpenWRT without problems.

Reverting to factory firmware:

Hard-reset the router three times to force it to boot from 'B.' This is
where the stock firmware resides. To remove any traces of OpenWRT from
your router simply flash the OEM image at this point.

With thanks to Leon Poon (@LeonPoon) for the initial bringup.

6d23e474ad ramips: add support for Amped Wireless ALLY router and extender
Amped Wireless ALLY is a whole-home WiFi kit, with a router (model
ALLY-R1900K) and an Extender (model ALLY-00X19K).  Both are devices are
11ac and based on MediaTek MT7621AT and MT7615N chips.  The units are
nearly identical, except the Extender lacks a USB port and has a single
Ethernet port.

Specification:
- SoC: MediaTek MT7621AT (2C/4T) @ 880MHz
- RAM: 128MB DDR3 (Nanya NT5CC64M16GP-DI)
- FLASH: 128MB NAND (Winbond W29N01GVSIAA)
- WiFi: 2.4/5 GHz 4T4R
  - 2.4GHz MediaTek MT7615N bgn
  - 5GHz MediaTek MT7615N nac
- Switch: SoC integrated Gigabit Switch
- USB: 1x USB3 (Router only)
- BTN: Reset, WPS
- LED: single RGB
- UART:  through-hole on PCB.
   J1: pin1 (square pad, towards rear)=3.3V, pin2=RX,
   pin3=GND, pin4=TX.  Settings: 57600/8N1.

Note regarding dual system partitions
-------------------------------------

The vendor firmware and boot loader use a dual partition scheme.  The boot
partition is decided by the bootImage U-boot environment variable: 0 for
the 1st partition, 1 for the 2nd.

OpenWrt does not support this scheme and will always use the first OS
partition.  It will set bootImage to 0 during installation, making sure
the first partition is selected by the boot loader.

Also, because we can't be sure which partition is active to begin with, a
2-step flash process is used.  We first flash an initramfs image, then
follow with a regular sysupgrade.

Installation:

Router (ALLY-R1900K)
1) Install the flashable initramfs image via the OEM web-interface.
  (Alternatively, you can use the TFTP recovery method below.)
  You can use WiFi or Ethernet.
  The direct URL is:  http://192.168.3.1/07_06_00_firmware.html
  a. No login is needed, and you'll be in their setup wizard.
  b. You might get a warning about not being connected to the Internet.
  c. Towards the bottom of the page will be a section entitled "Or
  Manually Upgrade Firmware from a File:" where you can manually choose
  and upload a firmware file.
  d: Click "Choose File", select the OpenWRT "initramfs" image and click
  "Upload."
2) The Router will flash the OpenWrt initramfs image and reboot.  After
  booting, LuCI will be available on 192.168.1.1.
3) Log into LuCI as root; there is no password.
4) Optional (but recommended) is to backup the OEM firmware before
  continuing; see process below.
5) Complete the Installation by flashing a full OpenWRT image.  Note:
  you may use the sysupgrade command line tool in lieu of the UI if
  you prefer.
  a.  Choose System -> Backup/Flash Firmware.
  b.  Click "Flash Image..." under "Flash new firmware image"
  c.  Click "Browse..." and then select the sysupgrade file.
  d.  Click Upload to upload the sysupgrade file.
  e.  Important:  uncheck "Keep settings and retain the current
      configuration" for this initial installation.
  f.  Click "Continue" to flash the firmware.
  g.  The device will reboot and OpenWRT is installed.

Extender (ALLY-00X19K)
1) This device requires a TFTP recovery procedure to do an initial load
  of OpenWRT.  Start by configuring a computer as a TFTP client:
  a. Install a TFTP client (server not necessary)
  b. Configure an Ethernet interface to 192.168.1.x/24; don't use .1 or .6
  c. Connect the Ethernet to the sole Ethernet port on the X19K.
2) Put the ALLY Extender in TFTP recovery mode.
  a. Do this by pressing and holding the reset button on the bottom while
  connecting the power.
  b. As soon as the LED lights up green (roughly 2-3 seconds), release
  the button.
3) Start the TFTP transfer of the Initramfs image from your setup machine.
For example, from Linux:
tftp -v -m binary 192.168.1.6 69 -c put initramfs.bin
4) The Extender will flash the OpenWrt initramfs image and reboot.  After
booting, LuCI will be available on 192.168.1.1.
5) Log into LuCI as root; there is no password.
6) Optional (but recommended) is to backup the OEM firmware before
  continuing; see process below.
7) Complete the Installation by flashing a full OpenWRT image.  Note: you
may use the sysupgrade command line tool in lieu of the UI if you prefer.
  a.  Choose System -> Backup/Flash Firmware.
  b.  Click "Flash Image..." under "Flash new firmware image"
  c.  Click "Browse..." and then select the sysupgrade file.
  d.  Click Upload to upload the sysupgrade file.
  e.  Important:  uncheck "Keep settings and retain the current
      configuration" for this initial installation.
  f.  Click "Continue" to flash the firmware.
  g.  The device will reboot and OpenWRT is installed.

Backup the OEM Firmware:
-----------------------

There isn't any downloadable firmware for the ALLY devices on the Amped
Wireless web site. Reverting back to the OEM firmware is not possible
unless we have a backup of the original OEM firmware.

The OEM firmware may be stored on either /dev/mtd3 ("firmware") or
/dev/mtd6 ("oem").  We can't be sure which was overwritten with the
initramfs image, so backup both partitions to be safe.

  1) Once logged into LuCI, navigate to System -> Backup/Flash Firmware.
  2) Under "Save mtdblock contents," first select "firmware" and click
  "Save mtdblock" to download the image.
  3) Repeat the process, but select "oem" from the pull-down menu.

Revert to the OEM Firmware:
--------------------------
* U-boot TFTP:
  Follow the TFTP recovery steps for the Extender, and use the
  backup image.

* OpenWrt "Flash Firmware" interface:
  Upload the backup image and select "Force update"
  before continuing.

Flash factory image through GUI.

This device has 2 partitions for the firmware called firmware and
alt_firmware. To successfully flash and boot the device, the device
should have been running from alt_firmware partition. To get the device
booted through alt_firmware partition, download the OEM firmware from
Linksys website and upgrade the firmware from web GUI. Once this is done,
flash the OpenWrt Factory firmware from web GUI.

Reverting to factory firmware:

1. Boot to 'alt_firmware'(where stock firmware resides) by doing one of
   the following:
   Press the "wps" button as soon as power LED turns on when booting.
   (OR) Hard-reset the router consecutively three times to force it to
   boot from 'alt_firmware'.
2. To remove any traces of OpenWRT from your router simply flash the OEM
   image at this point.

a46ad596a3 ramips: add support for TP-Link Archer C6U v1 (EU)
This patch adds support for TP-Link Archer C6U v1 (EU).
The device is also known in some market as Archer C6 v3.
This patch supports only Archer C6U v1 (EU).

Specifications:
--------------

* SoC: Mediatek MT7621AT 2C2T, 880MHz
* RAM: 128MB DDR3
* Flash: 16MB SPI NOR flash (Winbond 25Q128)
* WiFi 5GHz: Mediatek MT7613BEN (2x2:2)
* WiFi 2.4GHz: Mediatek MT7603EN (2x2:2)
* Ethernet: MT7630, 5x 1000Base-T.
* LED: Power, WAN, LAN, WiFi 2GHz and 5GHz, USB
* Buttons: Reset, WPS.
* UART: Serial console (115200 8n1), J1(GND:3)
* USB: One USB2 port.

Installation:
------------

Install the OpenWrt factory image for C6U is from the
TP-Link web interface.

1) Go to "Advanced/System Tools/Firmware Update".
2) Click "Browse" and upload the OpenWrt factory image:
openwrt-ramips-mt7621-tplink_archer-c6u-v1-squashfs-factory.bin.
3) Click the "Upgrade" button, and select "Yes" when prompted.

Recovery to stock firmware:
--------------------------

The C6U bootloader has a failsafe mode that provides a web
interface (running at 192.168.0.1) for reverting back to the
stock TP-Link firmware. The failsafe interface is triggered
from the serial console or on failed kernel boot. Unfortunately,
there's no key combination that enables the failsafe mode. This
gives us two options for recovery:

1) Recover using the serial console (J1 header).
The recovery interface can be selected by hitting 'x' when
prompted on boot.

2) Trigger the bootloader failsafe mode.
A more dangerous option is force the bootloader into
recovery mode by erasing the OpenWrt partition from the
OpenWrt's shell - e.g "mtd erase firmware". Please be
careful, since erasing the wrong partition can brick
your device.

WARNING!!

ISP managed firmware might at any time update itself to a version
where all known workarounds have been disabled.  Never boot an ISP
managed firmware with a SIM in any of the slots if you intend to use
the router with OpenWrt. The bootloader lock can only be disabled with
root access to running firmware. The flash chip is physically
inaccessible without soldering.

Installation from OEM web GUI:

- Log in as "supervisor" on https://172.17.1.1/
- Upload OpenWrt initramfs-recovery.bin image on the
  Maintenance -> Firmware page
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- (optional) Copy OpenWrt to the recovery partition. See below
- Sysupgrade to the OpenWrt sysupgrade image and reboot

Installation from OEM ssh:

- Log in as "root" on 172.17.1.1 port 22022
- scp OpenWrt initramfs-recovery.bin image to 172.17.1.1:/tmp
- Prepare bootloader config by running:
    nvram setro uboot DebugFlag 0x1
    nvram setro uboot CheckBypass 0
    nvram commit
- Run "mtd_write -w write initramfs-recovery.bin Kernel" and reboot
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- (optional) Copy OpenWrt to the recovery partition. See below
- Sysupgrade to the OpenWrt sysupgrade image and reboot

Copying OpenWrt to the recovery partition:

- Verify that you are running a working OpenWrt recovery image
  from flash
- ssh to root@192.168.1.1 and run:
    fw_setenv CheckBypass 0
    mtd -r erase Kernel2
- Wait while the bootloader mirrors Image1 to Image2

NOTE: This should only be done after successfully booting the OpenWrt
  recovery image from the primary partition during installation.  Do
  not do this after having sysupgraded OpenWrt!  Reinstalling the
  recovery image on normal upgrades is not required or recommended.

Installation from Z-Loader:

- Halt boot by pressing Escape on console
- Set up a tftp server to serve the OpenWrt initramfs-recovery.bin
  image at 10.10.10.3
- Type "ATNR 1,initramfs-recovery.bin" at the "ZLB>" prompt
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- Sysupgrade to the OpenWrt sysupgrade image

NOTE: ATNR will write the recovery image to both primary and recovery
  partitions in one go.

Booting from RAM:

- Halt boot by pressing Escape on console
- Type "ATGU" at the "ZLB>" prompt to enter the U-Boot menu
- Press "4" to select "4: Entr boot command line interface."
- Set up a tftp server to serve the OpenWrt initramfs-recovery.bin
  image at 10.10.10.3
- Load it using "tftpboot 0x88000000 initramfs-recovery.bin"
- Boot with "bootm  0x8800017C" to skip the 380 (0x17C) bytes ZyXEL
  header

This method can also be used to RAM boot OEM firmware. The warning
regarding OEM applies!  Never boot an unknown OEM firmware, or any OEM
firmware with a SIM in any slot.

NOTE: U-Boot configuration is incomplete (on some devices?). You may
  have to configure a working mac address before running tftp using
   "setenv eth0addr <mac>"

Unlocking the bootloader:

If you are unebale to halt boot, then the bootloader is locked.

The OEM firmware locks the bootloader on every boot by setting
DebugFlag to 0.  Setting it to 1 is therefore only temporary
when OEM firmware is installed.

- Run "nvram setro uboot DebugFlag 0x1; nvram commit" in OEM firmware
- Run "fw_setenv DebugFlag 0x1" in OpenWrt

  NOTE:
    OpenWrt does this automatically on first boot if necessary

  NOTE2:
    Setting the flag to 0x1 avoids the reset to 0 in known OEM
    versions, but this might change.

  WARNING:
    Writing anything to flash while the bootloader is locked is
    considered extremely risky. Errors might cause a permanent
    brick!

Enabling management access from LAN:

Temporary workaround to allow installing OpenWrt if OEM firmware
has disabled LAN management:

- Connect to console
- Log in as "root"
- Run "iptables -I INPUT -i br0 -j ACCEPT"

Notes on the OEM/bootloader dual partition scheme

The dual partition scheme on this device uses Image2 as a recovery
image only. The device will always boot from Image1, but the
bootloader might copy Image2 to Image1 under specific conditions. This
scheme prevents repurposing of the space occupied by Image2 in any
useful way.

Validation of primary and recovery images is controlled by the
variables CheckBypass, Image1Stable, and Image1Try.

The bootloader sets CheckBypass to 0 and reboots if Image1 fails
validation.

If CheckBypass is 0 and Image1 is invalid then Image2 is copied to
Image1.

If CheckBypass is 0 and Image2 is invalid, then Image1 is copied to
Image2.

If CheckBypass is 1 then all tests are skipped and Image1 is booted
unconditionally.  CheckBypass is set to 1 after each successful
validation of Image1.

Image1Try is incremented if Image1Stable is 0, and Image2 is copied to
Image1 if Image1Try is 3 or larger.  But the bootloader only tests
Image1Try if CheckBypass is 0, which is impossible unless the booted
image sets it to 0 before failing.

The system is therefore not resilient against runtime errors like
failure to mount the rootfs, unless the kernel image sets CheckBypass
to 0 before failing. This is not yet implemented in OpenWrt.

Setting Image1Stable to 1 prevents the bootloader from updating
Image1Try on every boot, saving unnecessary writes to the environment
partition.

Keeping an OpenWrt initramfs recovery as Image2 is recommended
primarily to avoid unwanted OEM firmware boots on failure. Ref the
warning above. It enables console-less recovery in case of some
failures to boot from Image1.

85b1f4d8ca treewide: remove execute bit and shebang from board.d files
So far, board.d files were having execute bit set and contained a
shebang. However, they are just sourced in board_detect, with an
apparantly unnecessary check for execute permission beforehand.

Replace this check by one for existance and make the board.d files
"normal" files, as would be expected in /etc anyway.

Note:

This removes an apparantly unused '#!/bin/sh /etc/rc.common' in

1e75909a35 ramips: mt7621: add TP-Link EAP235-Wall support
The TP-Link EAP235-Wall is a wall-mounted, PoE-powered AC1200 access
point with four gigabit ethernet ports.

When connecting to the device's serial port, it is strongly advised to
use an isolated UART adapter. This prevents linking different power
domains created by the PoE power supply, which may damage your devices.

The device's U-Boot supports saving modified environments with
`saveenv`. However, there is no u-boot-env partition, and saving
modifications will cause the partition table to be overwritten. This is
not an issue for running OpenWrt, but will prevent the vendor FW from
functioning properly.

Device specifications:
* SoC: MT7621DAT
* RAM: 128MiB
* Flash: 16MiB SPI-NOR
* Wireless 2.4GHz (MT7603EN): b/g/n, 2x2
* Wireless 5GHz (MT7613BEN): a/n/ac, 2x2
* Ethernet: 4× GbE
  * Back side: ETH0, PoE PD port
  * Bottom side: ETH1, ETH2, ETH3
* Single white device LED
* LED button, reset button (available for failsafe)
* PoE pass-through on port ETH3 (enabled with GPIO)

Datasheet of the flash chip specifies a maximum frequency of 33MHz, but
that didn't work. 20MHz gives no errors with reading (flash dump) or
writing (sysupgrade).

Device mac addresses:
Stock firmware uses the same MAC address for ethernet (on device label)
and 2.4GHz wireless. The 5GHz wireless address is incremented by one.
This address is stored in the 'info' ('default-mac') partition at an
offset of 8 bytes.
From OEM ifconfig:
    eth     a4:2b:b0:...:88
    ra0     a4:2b:b0:...:88
    rai0    a4:2b:b0:...:89

Flashing instructions:
* Enable SSH in the web interface, and SSH into the target device
* run `cliclientd stopcs`, this should return "success"
* upload the factory image via the web interface

Debricking:
U-boot can be interrupted during boot, serial console is 57600 baud, 8n1
This allows installing a sysupgrade image, or fixing the device in
another way.
* Access serial header from the side of the board, close to ETH3,
  pin-out is (1:TX, 2:RX, 3:GND, 4:3.3V), with pin 1 closest to ETH3.
* Interrupt bootloader by holding '4' during boot, which drops the
  bootloader into its shell
* Change default 'serverip' and 'ipaddr' variables (optional)
* Download initramfs with `tftpboot`, and boot image with `bootm`
    # tftpboot 84000000 openwrt-initramfs.bin
    # bootm

Revert to stock:
Using the tplink-safeloader utility from the firmware-utils package,
TP-Link's firmware image can be converted to an OpenWrt-compatible
sysupgrade image:
  $ ./staging_dir/host/bin/tplink-safeloader -B EAP235-WALL-V1 \
      -z EAP235-WALLv1_XXX_up_signed.bin -o eap235-sysupgrade.bin

This can then be flashed using the OpenWrt sysupgrade interface. The
image will appear to be incompatible and must be force flashed, without
keeping the current configuration.

Known issues:
- DFS support is incomplete (known issue with MT7613)
- MT7613 radio may stop responding when idling, reboot required.
  This was an issue with the ddc75ff704 version of mt76, but appears to
  have improved/disappeared with bc3963764d.

256M DDR3
32M SPI-NOR
MediaTek MT7603 2T2R 802.11n 2.4GHz
MediaTek MT7915 2T2R 802.11ax 5GHz

Not Working
-----------
 - Bluetooth (connected to UART3)

UART
----

UART is located in the lower left corner of the board. Pinout is

0 - 3V3 (don't connect)
1 - RX
2 - TX
3 - GND

Console is 115200 8N1.

Boot
----

1. Connect to the serial console and connect power.

2. Double-press ESC when prompted

3. Set the fdt address

   $ fdt addr $(fdtcontroladdr)

4. Remove the signature node from the control FDT

   $ fdt rm /signature

5. Transfer and boot the OpenWrt initramfs image to the device.
   Make sure to name the file C0A80114.img and have it reachable at
   192.168.1.1/24

   $ tftpboot; bootm

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

1. Connect to the booted device at 192.168.1.20 using username/password
   "ubnt".

2. Update the bootloader environment.

   $ fw_setenv devmode TRUE
   $ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr);
     fdt rm /signature; bootubnt"
   $ fw_setenv bootcmd "run boot_openwrt"

3. Transfer the OpenWrt sysupgrade image to the device using SCP.

4. Check the mtd partition number for bs / kernel0 / kernel1

   $ cat /proc/mtd

5. Set the bootselect flag to boot from kernel0

   $ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4

6. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1

   $ dd if=openwrt.bin of=/dev/mtdblock6
   $ dd if=openwrt.bin of=/dev/mtdblock7

7. Reboot the device. It should boot into OpenWrt.

Below are the original installation instructions prior to the discovery
of "devmode=TRUE". They are not required for installation and are
documentation only.

The bootloader employs signature verification on the FIT image
configurations. This way, booting unauthorized image without patching
the bootloader is not possible. Manually configuring the bootcmd in the
U-Boot envronment won't work, as this is restored to the default value
if modified.

The bootloader is made up of three different parts.

1. The SPL performing early board initialization and providing a XModem
   recovery in case the PBL is missing

2. The PBL being the primary U-Boot application and containing the
   control FDT. It is LZMA packed with a uImage header.

3. A Ubiquiti standalone U-Boot application providing the main boot
   routine as well as their recovery mechanism.

In a perfect world, we would only replace the PBL, as the SPL does not
perform checks on the PBLs integrity. However, as the PBL is in the same
eraseblock as the SPL, we need to at least rewrite both.

The bootloader will only verify integrity in case it has a "signature"
node in it's control device-tree. Renaming the signature node to
something else will prevent this from happening.

Warning: These instructions are based on the firmware intially
shipped with the device and potentially brick your device in a way it
can only be recovered using a SPI flasher.

Only (!) proceed if you understand this!

1. Extract the bootloader from the U-Boot partition using the OpenWrt
   initramfs image.

2. Split the bootloader into it's 3 components:

   $ dd if=bootloader.bin of=spl.bin bs=1 skip=0 count=45056
   $ dd if=bootloader.bin of=pbl.uimage bs=1 skip=45056 count=143360
   $ dd if=bootloader.bin of=ubnt.uimage bs=1 skip=188416

3. Strip the uImage header from the PBL

   $ dd if=pbl.uimage of=pbl.lzma bs=64 skip=1

4. Decompress the PBL

   $ lzma -d pbl.lzma --single-stream

   The decompressed PBL sha256sum should be
   d8b406c65240d260cf15be5f97f40c1d6d1b6e61ec3abed37bb841c90fcc1235

5. Open the decompressed PBL using your favorite hexeditor. Locate the
   control FDT at offset 0x4CED0 (0xD00DFEED). At offset 0x4D5BC, the
   label for the signature node is located. Rename the "signature"
   string at this offset to "signaturr".

   The patched PBL sha256sum should be
   d028e374cdb40ba44b6e3cef2e4e8a8c16a3b85eb15d9544d24fdd10eed64c97

6. Compress the patched PBL

   $ lzma -z pbl --lzma1=dict=67108864

   The resulting pbl.lzma file should have the sha256sum
   7ae6118928fa0d0b3fe4ff81abd80ecfd9ba2944cb0f0a462b6ae65913088b42

7. Create the PBL uimage

   $ SOURCE_DATE_EPOCH=1607909492 mkimage -A mips -O u-boot -C lzma
     -n "U-Boot 2018.03 [UniFi,v1.1.40.71]" -a 84000000 -e 84000000
     -T firmware -d pbl.lzma patched_pbl.uimage

   The resulting patched_pbl.uimage should have the sha256sum
   b90d7fa2dcc6814180d3943530d8d6b0d6a03636113c94e99af34f196d3cf2ce

8. Reassemble the complete bootloader

   $ dd if=patched_pbl.uimage of=aligned_pbl.uimage bs=143360 count=1
     conv=sync
   $ cat spl.bin > patched_uboot.bin
   $ cat aligned_pbl.uimage >> patched_uboot.bin
   $ cat ubnt.uimage >> patched_uboot.bin

   The resulting patched_uboot.bin should have the sha256sum
   3e1186f33b88a525687285c2a8b22e8786787b31d4648b8eee66c672222aa76b

9. Transfer your patched bootloader to the device. Also install the
   kmod-mtd-rw package using opkg and load it.

   $ insmod mtd-rw.ko i_want_a_brick=1

   Write the patched bootloader to mtd0

   $ mtd write patched_uboot.bin u-boot

10. Erase the kernel1 partition, as the bootloader might otherwise
    decide to boot from there.

    $ mtd erase kernel1

11. Transfer the OpenWrt sysupgrade image to the device and install
    using sysupgrade.

7a181a65f2 treewide: fix initramfs detection
Commit "initramfs: switch to tmpfs to fix ujail" switched initramfs to
now use tmpfs, it causes $(rootfs_type) to now return tmpfs when
running initramfs image instead of being empty.

This broke initramfs detection which is required so that when installing
on MikroTik devices firmware partition would first get erased fully
before writing.

So, lets test for $(rootfs_type) returning "tmpfs" instead.

a51e46e543 ramips: add Xiaomi Mi Router 4A Gigabit explicitly
This device has previously been supported by the image
for Xiaomi Mi Router 3G v2. Since this is not obvious, the
4A is marketed as a new major revision and it also seems to
have a different bootloader, this will be both more tidy and
more helpful for the users.

Apart from that, note that there also is a 100M version of
the device that uses mt7628 platform, so a specifically named
image will also prevent confusion in this area.

Specifications:

- SoC:      MediaTek MT7621
- Flash:    16 MiB NOR SPI
- RAM:      128 MiB DDR3
- Ethernet: 3x 10/100/1000 Mbps (switched, 2xLAN + WAN)
- WIFI0:    MT7603E 2.4GHz 802.11b/g/n
- WIFI1:    MT7612E 5GHz 802.11ac
- Antennas: 4x external (2 per radio), non-detachable
- LEDs:     Programmable "power" LED (two-coloured, yellow/blue)
            Non-programmable "internet" LED (shows WAN activity)
- Buttons:  Reset

Installation:

Bootloader won't accept any serial input unless "boot_wait" u-boot
environment variable is changed to "on".

Vendor firmware won't accept any serial input until "uart_en" is
set to "1".

Using the https://github.com/acecilia/OpenWRTInvasion exploit you
can gain access to shell to enable these options:

To enable uart keyboard actions - 'nvram set uart_en=1'
To make uboot delay boot work - 'nvram set boot_wait=on'
Set boot delay to 5 - 'nvram set bootdelay=5'

Then run 'nvram commit' to make the changes permanent.

Once in the shell (following the OpenWRTInvasion instructions) you
can then run the following to flash OpenWrt and then reboot:

'cd /tmp; curl https://downloads.openwrt.org/...-sysupgrade.bin
  --output firmware.bin; mtd -e OS1 -r write firmware.bin OS1'

2230fe3922 ramips: remove set_wifi_led function in 01_leds
While we mostly use the ucidef_set_led_* functions directly in 01_leds
we still have the set_wifi_led function in parallel for several old
devices. This is not only inconsistent with the other definitions,
it also links to the wlan0 interface instead of using a phy trigger
which would be independent of the interface name (and is used for
all newer devices anyway). Apart from that, the standard names
"wifi" and "wifi-led" are not very helpful in a world with different
radio bands either.

Thus, this patch removes the set_wifi_led function and puts the
relevant commands into the cases explicitly. This makes the
mechanism used more evident and will hopefully lead to some future
improvements or at least prevent some copy-pasting of the old
setups.

ed5933beb6 ramips: remove option to set WiFi LED via aliases
In ramips, it's not common to use an alias for specifying the WiFi
LED; actually only one device uses this mechanism (TL-WR841N v14).

Particularly since the WiFi LEDs are typically distinguished between
2.4G and 5G etc. it is also not very useful for this target.

Thus, this patch removes the setup lines for this mechanism and
converts the TL-WR841N v14 to the normal setup.

Like in the previous patch for ath79 target, this will remove the
"devicename" from LED labels in ramips as well.

The devicename is removed in DTS files and 01_leds, consolidation
of definitions into DTSI files is done where (easily) possible,
and migration scripts are updated.

For the latter, all existing definitions were actually just
devicename migrations anyway. Therefore, those are removed and
a common migration file is created in target base-files. This is
actually another example of how the devicename removal makes things

Installation:

Flash factory image through GUI.

This might fail due to the A/B nature of this device. When flashing, OEM
firmware writes over the non-booted partition. If booted from 'A',
flashing over 'B' won't work. To get around this, you should flash the
OEM image over itself. This will then boot the router from 'B' and
allow you to flash OpenWRT without problems.

Reverting to factory firmware:

Hard-reset the router three times to force it to boot from 'B.' This is
where the stock firmware resides. To remove any traces of OpenWRT from
your router simply flash the OEM image at this point.

Backup the OEM Firmware:
-----------------------

There isn't any firmware released for the WL-WN531A6 on
the Wavlink web site. Reverting back to the OEM firmware is
not possible unless we have a backup of the original OEM
firmware.

The OEM firmware is stored on /dev/mtd4 ("Kernel").

  1) Plug a FAT32 formatted USB flash drive into the USB port.
  2) Navigate to "Setup->USB Storage". Under the "Available
     Network folder" you can see part of the mount point of
     the newly mounted flash drive filesystem - e.g "sda1".
     The full mount point is prefixed with "/media", so in
     this case the mount point becomes "/media/sda1".
  3) Go to http://192.168.10.1/webcmd.shtml .
  4) Type the following line in the "Command" input box:

     dd if=/dev/mtd4ro of=/media/sda1/firmware.bin

  5) Click "Apply"
  6) After few seconds, in the text area should appear this
     output:

        30080+0 records in
      30080+0 records out

  7) Type "sync" in the "Command" input box and click "Apply".
  8) At this point the OEM firmware is stored on the flash
     drive as "firmware.bin". The size of the file is 15040 KB.

Installation:
------------

* Flashing instructions (OEM web interface):
The OEM web interface accepts only files with names containing
"WN531A6". It's also impossible to flash the *-sysupgrade.bin
image, so we have to flash the *-initramfs-kernel.bin first and
use the OpenWrt's upgrade interface to write the sysupgrade
image.

  1) Rename openwrt-ramips-mt7621-wavlink_wl-wn531a6-initramfs-kernel.bin
     to WN531A6.bin.
  2) Connect your computer to the one of the LAN ports of the
     router with an Ethernet cable and open http://192.168.10.1
  3) Browse to Setup -> Firmware Upgrade interface.
  4) Upload the (renamed) OpenWrt image - WN531A6.bin.
  5) Proceed with the firmware installation and give the device
     a few minutes to finish and reboot.
  6) After reboot wait for the "WAVLINK" logo on the top cover
     to turn solid blue, and open http://192.168.1.1
  7) Use the OpenWrt's "Flash Firmware" interface to write the
     OpenWrt sysupgrade image:
     openwrt-ramips-mt7621-wavlink_wl-wn531a6-squashfs-sysupgrade.bin

* Flashing instructions (u-boot TFTP):
  1) Configure a TFTP server on your computer and set its IP
     to 192.168.10.100
  2) Rename the OpenWrt sysupgrade image to firmware.bin and
     place it in the root folder of the TFTP server.
  3) Power off the device and connect an Ethernet cable from
     one of its LAN ports your computer.
  4) Press the "Reset" button (and keep it pressed)
  5) Power on the device.
  6) After a few seconds, when the connected port LAN LED stops
     blinking fast, release the "Reset" button.
  7) Flashing OpenWrt takes less than a minute, system will
     reboot automatically.
  8) After reboot the WAVLINK logo on the top cover will indicate
     the current OpenWrt running status (wait until the logo tunrs
     solid blue).

Revert to the OEM Firmware:
--------------------------
* U-boot TFTP:
  Follow "Flashing instructions (u-boot TFTP)" and use the
  "firmware.bin" backup image.

* OpenWrt "Flash Firmware" interface:
  Upload the "firmware.bin" backup image and select "Force update"
  before continuing.

Notes:
-----
* The MAC address shown on the label at the back of the device
is assigned to the 2.4G WiFi adapter.

  MAC addresses assigned by the OEM firmware:
  2.4G: *:XX (label): factory@0x0004
    5G: *:XX + 1    : factory@0x8004
   WAN: *:XX - 1    : factory@0xe006
   LAN: *:XX - 2    : factory@0xe000

* The I2C bus and UART2 are fully functional. The headers are
not populated.

a14f5bb4bd treewide: use wpad-basic-wolfssl as default
In order to support SAE/WPA3-Personal in default images. Replace almost
all occurencies of wpad-basic and wpad-mini with wpad-basic-wolfssl for
consistency. Keep out ar71xx from the list as it won't be in the next
release and would only make backports harder.

Build-tested (build-bot settings):
ath79: generic, ramips: mt7620/mt76x8/rt305x, lantiq: xrx200/xway,
sunxi: a53

03cdbb2040 ramips: fix LED labels for Asus RT-AC65P
The leds block was copied over from the RT-AC85P DTS to the common
DTSI while keeping the device-specific model name in the label.

This moves the LEDs back to the DTS files and adjusts the names to
properly resemble the model name of the devices used at, just like
it is handled on most other devices.

74438d5419 ramips: add support for MikroTik RouterBOARD 760iGS (hEX S)
This patch adds support for the MikroTik RouterBOARD 760iGS router.
It is similar to the already supported RouterBOARD 750Gr3.
The 760iGS device features an added SFP cage, and passive
PoE out on port 5 compared to the RB750Gr3.

https://mikrotik.com/product/hex_s

Specifications:

- SoC: MediaTek MT7621A
- CPU: 880MHz
- Flash: 16 MB
- RAM:  256 MB
- Ethernet: 5x 10/100/1000 Mbps
- SFP cage
- USB port
- microSD slot

Unsupported:

- Beeper (requires PWM driver)
- ZT2046Q (ADS7846 compatible) on SPI as slave 1 (CS1)
  The linux driver requires an interrupt, and pendown GPIO
  These are unknown, and not needed with the touchscreen
  only used for temperature and voltage monitoring.
  ads7846 hwmon:
  temp0 is degrees Celsius
  temp1 is voltage * 32

GPIOs:

- 07:  input passive PoE out (lan5) compatible (Mikrotik) device connected
- 17:  output passive PoE out (lan5) switch

Installation through RouterBoot follows the usual MikroTik method
https://openwrt.org/toh/mikrotik/common

To boot to intramfs image in RAM:

1. Setup TFTP server to serve intramfs image.
2. Plug Ethernet cable into WAN port.
3. Unplug power, hold reset button and plug power in.
   Wait (~25 seconds) for beep and then release reset button.
   The SFP LED will be lit in RouterBoot, but will not be lit in OpenWRT.
4. Wait for a minute. Router should be running OpenWrt,
   check by plugging in to port 2-5 and going to 192.168.1.1.

To install OpenWrt to flash:

1. Follow steps above to boot intramfs image in RAM.
2. Flash the sysupgrade.bin image with web interface or sysupgrade.
3. Once the router reboots you will be running OpenWrt from flash.

OEM firmware differences:

- RouterOS assigns a different MAC address for each port
- The first address (E01 on the sticker) is used for wan (ether1 in OEM).
- The next address is used for lan2.
- The last address (E06 on the sticker) is used for sfp.
