ec45f2f246 ramips: rename mtd partition of ipTIME NAND devices
Contrary to common ipTIME NOR devices, the "Config" partition of T5004
and AX2004M contain normal U-Boot environment variables. Renaming the
partition into "u-boot-env" serves for better description, and it also
conforms to common naming practice in OpenWrt.

This patch might also be extended to A3004T, but its u-boot-env
partition layout has not been confirmed yet.

7e04a611bc ramips: add NMBM support for ipTIME AX2004M
AX2004M uses NMBM on its NAND flash, but it was not enabled in DTS as the
device support [1] had been added before NMBM feature in mtk_bmt driver [2].
Let's enable it now.

With this change, there is a low possibility of boot failure after
sysupgrade from older versions. As AX2004M already has gone through
two stable releases in the meantime, it would be safe to warn users
by bumping DEVICE_COMPAT_VERSION.

2a0c9cc8cd ramips: add support for TP-Link EX220 v1
This device is very similar, if not identical, to the TP-Link AX23 v1
but is targeted at service providers and features a completely different
flash layout.

Hardware
--------

CPU:    MediaTek MT7621 DAT
RAM:    128MB DDR3 (integrated)
FLASH:  16MB SPI-NOR
WiFi:   MediaTek MT7905 + MT7975 (2.4 / 5 DBDC) 802.11ax
SERIAL: 115200 8N1
        LEDs - (3V3 - GND - RX - TX) - ETH ports

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

Flashing is only possible via a serial connection using the sysupgrade
image; the factory image must be signed. You can flash the sysupgrade
image directly through the U-Boot console, or preferably, by booting the
initramfs image and flashing with the sysupgrade command. Follow these
steps for sysupgrade flashing:

1. Establish a UART serial connection.
2. Set up a TFTP server at 192.168.0.2 and copy the initramfs image
   there.
3. Power on the device and press any key to interrupt normal boot.
4. Load the initramfs image using tftpboot.
5. Boot with bootm.
6. If you haven't done so already, back up all stock mtd partitions.
7. Copy the sysupgrade image to the router.
8. Flash OpenWrt through either LuCI or the sysupgrade command. Remember
   not to attempt saving settings.

Revert to stock firmware
------------------------

Flash stock firmware via OEM web-recovery mode. If you don't have access
to the stock firmware image, you will need to restore the firmware
partition backed up earlier.

Web-Recovery
------------

The router supports an HTTP recovery mode:

1. Turn off the router.
2. Press the reset button and power on the device.
3. When all LEDs start flashing, release reset and quickly press it
   again.

The interface is reachable at 192.168.0.1 and supports installation of
the OEM factory image. Note that flashing OpenWrt this way is not
possible, as mentioned above.

A typo snuck in with the addition of Cudy M1800, changing
"nr7101" to "nt7101". The result is a default network config
for NR7101 without the only ethernet interface on the NR7101,
thereby soft bricking it.

Flash instructions for web-based U-Boot recovery:

1. Power the device with WPS button pressed and wait around 10 seconds.
2. Setup static IP 192.168.1.2/24 on your PC.
3. Go to 192.168.1.1 in browser and upload 'recovery' image.

The device runs LEDE 17.01 (kernel 4.4.x) based firmware with 'failsafe'
mode available which allows alternative upgrade method:

1. Run device in 'failsafe' mode and change password for default user.
2. SSH to the device, transfer 'sysupgrade' image and perform upgrade
   in forced mode, without preserving settings: 'sysupgrade -n -F ...'.

Other notes:

If you own early version of this device, the vendor firmware might
refuse OpenWrt image because of missing custom header. In that case,
ask vendor's customer support for stock firmware without custom header
support/requirement.

a4eb1ea331 ramips: add support for D-Link DRA-1360
The DRA-1360 rev A is a wall-plug AC1300 repeater.
Hardware is identical (same FCC ID, black case instead of white)
to D-Link DAP-1620 rev B, which is already supported, but a
different model name, revision, and hardware ID are needed.
Thus, the bulk of the DAP-1620 device tree is extracted to a
common dtsi included by the two models' device trees.

Repeating specs and installation instructions from e4c7703:
(note that the RAM size mentioned there was incorrect, oops)

- Ethernet: 1 RJ45 port 10/100/1000
- Power/status LED: red+green
- LED RSSI bargraph: 2x green, 1x red+green

Installation:
- Keep reset button pressed during plug-in
- Web Recovery Updater is at 192.168.0.50

ac68fbf526 ramips: add support for I-O DATA WN-DEAX1800GR
I-O DATA WN-DEAX1800GR is a 2.4/5 GHz band 11ax (Wi-Fi 6) router, based
on MT7621A.

Specification:

- SoC         : MediaTek MT7621A
- RAM         : DDR3 256 MiB (Nanya NT5CC128M16JR-EK)
- Flash       : RAW NAND 128 MiB (Winbond W29N01HVSINF)
- WLAN        : 2.4/5 GHz (MediaTek MT7915)
- Ethernet    : 5x 10/100/1000 Mbps
  - Switch    : MT7530 (SoC)
- LEDs/Keys   : 6x/3x
- UART        : through-hole on PCB (J2)
  - assignment: 3.3V, GND, TX, RX from "1" marking
  - settings  : 115200n8
- Power       : 12 VDC, 1 A

Flash instruction using initramfs-factory image:

1. Boot WN-DEAX1800GR normally
2. Access to "http://192.168.0.1/" and open firmware update page
   ("ファームウェア")
3. Select the OpenWrt initramfs-factory.bin image and click update
   ("更新") button to perform firmware update
4. On the initramfs image, perform sysupgrade with the
   squashfs-sysupgrade.bin image
5. Wait ~120 seconds to complete flashing

Note:

- This device has 2x OS images on the flash storage. In this support,
  the first one will be used.

Warning:

- Do not use "saveenv" command on U-Boot CLI.
  This device has wrong u-boot-env data. The actual length of individual
  env data installed to the device is 0x1000 (4 KiB), but installed
  U-Boot requires 0x20000 (128 KiB). So U-Boot determines the data is
  invalid. Then, if you perform saving environment data with saveenv on
  U-Boot CLI, installed env data will be overwritten with too few
  default values without individual values (SSID, password, MAC
  addresses, etc...).

MAC addresses:

LAN    : 50:41:B9:xx:xx:F4 (Config, ethaddr (text))
WAN    : 50:41:B9:xx:xx:F6 (Config, wanaddr (text))
2.4 GHz: 50:41:B9:xx:xx:F4 (Config, rmac (text) / Factory, 0x4 (hex))
5 GHz  : 50:41:B9:xx:xx:F5 (none)

8bf9a8a5e6 ramips: add wan2 support for MQmaker WiTi
The PHY of the wan2 port on MQmaker WiTi is wired to the second MAC of the
SoC. Rename the wan interface to wan1 and define it under the switch node,
effectively disabling the PHY muxing of the MT7530 switch's phy4.

Define the PHY of the wan2 port and adjust the gmac1 node accordingly. Now
that the PHY muxing feature is not being used anymore, the wan2 port can be
used to achieve 2 Gbps total bandwidth to the CPU.

11588c52b4 ramips: mt7621: add TP-Link EAP613 v1
The TP-Link EAP613 v1 is a ceiling-mount 802.11ax access point. It can
be powered via PoE or a DC barrel connector (12V). Connecting to the
UART requires fine soldering and careful manipulation of any soldered
wires.

Device details:
  * SoC: MT7621AT
  * Flash: 16 MiB SPI NOR
  * RAM: 256 MiB DDR3L
  * Wi-Fi:
    * MT7905DA + MT7975D: 2.4 GHz + 5 GHz (DBDC), 2x2:2
    * Two stamped metal antennas (ANT1, ANT2)
    * One PCB antenna (ANT3)
    * One unpopulated antenna (ANT4)
  * Ethernet:
    * 1× 10/100/1000 Mbps port with PoE
  * LEDs:
    * Array of four blue LEDs with one control line
  * Buttons:
    * Reset
  * Board test points:
    * UART: next to CPU RF-shield and power circuits
    * JTAG: under CPU RF-shield (untested)
  * Watchdog: 3PEAK TPV706 (not implemented)

  Althought three antennas are populated, the MT7905DA does not support
  the additional Rx chain for background DFS detection (or Bluetooth)
  according to commit 6cbcc34f50 ("ramips: disable unsupported
  background radar detection").

MAC addresses:
  * LAN: 48:22:54:xx:xx:a2 (device label)
  * WLAN 2.4 GHz: 48:22:54:xx:xx:a2
  * WLAN 5 GHz: 48:22:54:xx:xx:a3

  The radio calibration blob stored in flash also contains valid MAC
  addresses for both radio bands (OUI 00:0c:43).

Factory install:
  1. Enable SSH on the device via web interface
  2. Log in with SSH, and run `cliclientd stopcs`
  3. Upload -factory.bin image via web interface. It may be necessary to
     shorten the filename of the image to e.g. 'factory.bin'.

Recovery:
  1. Open the device by unscrewing four screws from the backside
  2. Carefully remove board from the housing
  3. Connect to UART (3.3V):
    * Find test points labelled "VCC", "GND", "UART_TX", "UART_RX"
    * Solder wires to test points or connect otherwise. Be careful not
      to damage the PCB e.g. by pulling on soldered wires.
    * Open console with 115200n8 settings
  4. Interrupt bootloader and use tftpboot to start an initramfs:
        setenv ipaddr $DEVICE_IP
        setenv serverip $SERVER_IP
        tftpboot 84000000 openwrt-initramfs-kernel.bin
        bootm

  DO NOT use saveenv to store modified u-boot environment variables. The
  environment is saved at flash offset 0x30000, which erases part of the
  (secondary) bootloader.

  The device uses two bootloader stages. The first stage will load the
  second stage from a uImage stored at flash offset 0x10000. In case of
  a damaged second stage, the first stage should allow uploading a new
  image via y-modem (untested).

- RAM: 256MB DDR3
- NOR Flash: MX25L12833FM2I 16MB SPI Flash
- Wi-Fi 2.4Ghz: MT7603E
- Wi-Fi 5Ghz: MT7612E
- Switch: MT7530 4x 1Gbit Ports
- WWAN: Unisoc SL8563 based TOZED TL70-C LTE CAT6 cellular modem
- USB: 1x optional USB2.0 external port
- Switches/Buttons: WPS, Reset, Power Switch
- LEDs: Power, Wi-Fi, Data, Signal 1-5, Phone

Installation and TFTP Recovery:
- Connect to serial console.
- Boot initramfs image by choosing option 1 when U-Boot prompts.
- Install sysupgrade image via OpenWrt.

Serial Pins:
Located at the bottom right when looking from the front, right under the
Reset/WPS buttons. The pinout from the left is:

  Serial console @ 57600,8n1

Flash instructions:

Connect to serial console and start up the device. As the bootloader got
locked you need to type in a password to unlock U-Boot access.
When you see the following output on the console:

relocate_code Pointer at: 87f1c000

type in the super secure password:

1234567890

Then select TFTP boot from RAM by selecting option 1 in the boot menu.
As Linksys decided to leave out a basic TFTP configuration you need to
set server- & client ip as well as the image filename the device will
search for. You need to use the initramfs openwrt image for the TFTP
boot process.

Once openwrt has booted up, upload the sysupgrade image via scp and run
sysupgrade as normal.

28df7f7ff2 ramips: mt7621: add support for ZyXEL WSM20
The ZyXEL WSM20 aka Multy M1 is a cheap mesh router system by ZyXEL
based on the MT7621 CPU.

Specifications
==============

SoC: MediaTek MT7621AT (880MHz)
RAM: 256MiB
Flash: 128MiB NAND
Wireless: 802.11ax (2x2 MT7915E DBDC)
Ethernet: 4x 10/100/1000 (MT7530)
Button: 1x WPS, 1x Reset, 1x LED On/Off
LED: 7 LEDs (3x white, 2x red, 2x green)

MAC address assignment
======================

The MAC address assignment follows stock: The label MAC address is the LAN
MAC address, the WAN address is read from flash.

The WiFi MAC addresses are set in userspace to label MAC + 1 and label MAC
+ 2.

Installation (web interface)
============================

The device is cloud-managed, but there is a hidden local firmware upgrade
page in the OEM web interface. The device has to be registered in the
cloud in order to be able to access this page.

The system has a dual firmware design, there is no way to tell which
firmware is currently booted. Therefore, an -initramfs version is flashed
first.

1. Log into the OEM web GUI
2. Access the hidden upgrade page by navigating to
   https://192.168.212.1/gui/#/main/debug/firmwareupgrade
3. Upload the -initramfs-kernel.bin file and flash it
4. Wait for OpenWrt to boot and log in via SSH
5. Transfer the sysupgrade file via SCP
6. Run sysupgrade to install the image
7. Reboot and enjoy

NB: If the initramfs version was installed in RAS2, the sysupgrade script
sets the boot number to the first partition. A backup has to be performed
manually in case the OEM firwmare should be kept.

Installation (UART method)
==========================

The UART method is more difficult, as the boot loader does not have a
timeout set. A semi-working stock firmware is required to configure it:

1. Attach UART
2. Boot the stock firmware until the message about failsafe mode appears
3. Enter failsafe mode by pressing "f" and "Enter"
4. Type "mount_root"
5. Run "fw_setenv bootmenu_delay 3"
6. Reboot, U-Boot now presents a menu
7. The -initramfs-kernel.bin image can be flashed using the menu
8. Run the regular sysupgrade for a permanent installation

Changing the partition to boot is a bit cumbersome in U-Boot, as there is
no menu to select it. It can only be checked using mstc_bootnum. To change
it, issue the following commands in U-Boot:

   nand read 1800000 53c0000 800
   mw.b 1800004 1 1
   nand erase 53c0000 800
   nand write 1800000 53c0000 800

This selects FW1. Replace "mw.b 1800004 1 1" by "mw.b 1800004 2 1" to
change to the second slot.

Back to stock
=============

It is possible to flash back to stock, but a OEM firmware upgrade is
required. ZyXEL does not provide the link on its website, but the link
can be acquired from the OEM web GUI by analyzing the transferred JSON
objects.

It is then a matter of writing the firmware to Kernel2 and setting the
boot partition to FW2:

   mtd write zyxel.bin Kernel2
   echo -ne "\x02" | dd of=/dev/mtdblock7 count=1 bs=1 seek=4 conv=notrunc

From https://github.com/openwrt/openwrt/pull/12280#issuecomment-1489279860
On Ethernet and WLAN, NAPI is threaded for all queues. This means that the
processing work is not stuck on the CPU that fired the IRQ. Under heavy
load, IRQs get disabled anyway, so it should not matter at all which CPUs
the IRQs fire on.

Basic testing indicates this to be true. There's no speedup or slowdown.

Stock flash layout:
```

0x000000fb0000-0x000001000000 : "Private"
```
The kernel partition will be replaced with the OpenWrt image, the other
partitions are left untouched.

"Config2" seems to be the config storage used by the stock firmware.

"Private" is a 320kB empty JFFS2 partition that comes with the stock
firmware. One can get a larger space for OpenWrt by merging it with
"Kernel".

OpenWrt flash layout:
```
0x000000000000-0x000000030000 : "u-boot"
0x000000030000-0x000000040000 : "u-boot-env"

0x000000fb0000-0x000001000000 : "private_stock"
```

The OpenWrt image must have 96 bytes of padding in the header.

MAC addresses on OEM firmware:
|      		| location on the flash 	| notes    	|
|------		|-----------------------	|----------	|
| lan (eth2) 	| factory + 0xe000      	| on label 	|
| wan (eth3) 	| factory + 0xe006      	|          	|
| 2.4g (rax0) 	| not on flash          	| lan + 1  	|
| 5g (ra0) 	| not on flash          	| lan + 2  	|

Mac addresses of the 2.4g and 5g interface are stored as ASCII strings in
the u-boot-env partition, but they are not used. OpenWrt calculates
Wifi Mac addresses based on the LAN Mac.

Flash and test instructions:
Flash the encrypted image (available in the OpenWrt forum) through the
stock D-Dink web interface.

1. Open the case, and solder the 4-pin header near the WAN port.
2. Connect it to a USB-UART TTL (3.3V) adapter, no need to connect VCC.
3. Open a terminal emulator (e.g. `screen /dev/ttyUSB0` on linux) with
the settings mentioned above.
4. Setup a TFTP server on your PC that can serve
`xxx-ramips-mt7621-dlink_dir-853-a1-initramfs-kernel.bin`.
5. Connect any LAN port to your PC and set a static IPv4 address to
192.168.0.101 (netmask 255.255.255.0).
6. Power on the device and keeps pressing 1 until you see the prompt.
7. Use default IP addresses and enter the file name accordingly, then hit
enter.
8. Wait until it boots to OpenWrt, the default IP address is 192.168.1.1,
you need to change your PC network adapter to use DHCP in order to access
LUCI.
9. So far, the OpenWrt runs in RAM and the flash contents are not touched.
You can try OpenWrt without having to overwrite the stock firmware, a
reboot clears all changes.
10. Optionally, backup the stock firmware (the "firmware" partition) in
Luci.
11. To permantly install OpenWrt to the device , click
on "System -> Backup/Flash Firmware" in Luci and flash
`xxx-ramips-mt7621-dlink_dir-853-a1-squashfs-sysupgrade.bin`

Known problems:
* WLAN0 defaults to 5G after a fresh installation, to enable 2.4G network,
you need to config it manually in LUCI.

* If you see jffs2 related warnings/errors after updating from the stock
web interface, you need to do a reset in LUCI. The error will be gone after
a cold reboot.

  SoC: MediaTek MT7621AT (2 cores at 880 MHz, 4 threads)
  RAM: Kingston D1216ECMDXGJD (256 MB)
  Wireless 2.4 GHz: MediaTek MT7603EN
  Wireless 5 GHz: MediaTek MT7613BEN
  Flash: 16 MB SPI NOR

Installation:

Flash the *-factory.bin image in the U-Boot recovery webserver.
You can trigger this webserver by holding the reset button until the LED
flashes yellow, or by hooking up to serial pads on the board (clearly
labeled GND, RX and TX) and pressing `x` early in boot.

Once the factory image has been flashed, you can use the regular upgrade
procedure with sysupgrade images for subsequent flashes.

39e4f03fd3 ramips: mt7621: add support for Xiaomi Mi Router 4A Gigabit v2
Device is the same as Xiaomi Mi Router 4A Gigabit, except of:
- 5G WiFi is MT7663
- addresses of leds, wifi and eth ports are slightly changed

Specs:
  SoC:  MT7621
  CPU:  2 x 880 MHz
  ROM:  16 MB
  RAM:  128 MB
  WLAN: MT7603, MT7663

MAC addresses:
  WAN     ****  factory 0xe006 (label)
  LAN     *:f7  factory 0xe000
  2.4 GHz *:f8  factory 0x0000+0x4 (mtd-eeprom+0x4)
  5 GHz   *:f9  factory 0x8000+0x4 (mtd-eeprom+0x4)

Installation:

Factory firmware is based on a custom OpenWrt 17.x.
Installation is the same as for Xiaomi Mi Router 4A Gigabit.

Probably the easiest way to install is to use the script from
this repository: https://github.com/acecilia/OpenWRTInvasion/pull/155

In a more advanced case, you can do everything yourself:
- gain access to the device through one of the exploits described
  in the link above
- upload sysupgrade image to /tmp
- overwrite stock firmware:
  # mtd -e OS1 -r write /tmp/sysupgrade.bin OS1

Recovery:

Recovery procedure is the same as for Xiaomi Mi Router 4A Gigabit.
Possible options can be found here:
https://openwrt.org/inbox/toh/xiaomi/xiaomi_mi_router_4a_gigabit_edition

One of the ways is to use another router with OpenWrt:
- connect both routers by their LAN ports
- download stock firmware from [1]
- place it inside /tmp/test.bin on the main router
- configure PXE/TFTP on the main router
- power off 4Av2, hold Reset button, power on
- as soon as image download via TFTP starts, Reset can be released
- blinking blue wan LED will indicate the end of the flashing process,
  now router can be rebooted

setting is 57600-8-N-1. The board has an unpopulated 2.54mm straight pin
header.

The pinout is: VCC (the square), RX, TX, GND.

Installation
------------
See the Wiki page [1] for more details, it comes down to:

1. Open the device, take off the heat sink
2. Connect the SPI flash chip to a flasher, e.g. a Raspberry Pi. Also
   connect the RESET pin for stability (thanks @FPSUsername for reporting)
3. Make a backup in case you want to revert to stock later
4. Flash the squashfs-factory.trx file to offset 0x50000 of the flash
5. Ensure the bootpartition variable is set to 0 in the U-Boot
   environment located at 0x30000

Note that the U-Boot is password protected, this can optionally be
removed. See the forum [2] for more details.

The label address is stored in ASCII in the board_data partition

Notes
-----
- This device has a dual-boot partition scheme, but OpenWRT will claim
  both partitions for more storage space.

Known issues
------------
- 2g MAC address does not match stock due to missing support for that in
  macaddr_add
- Only the power LED is configured by default

c13263ca07 ramips: add support for D-Link DIR-1935 A1
Add support for D-Link DIR-1935 A1 based on similarities to DIR-882 A1,
DIR-867 A1 and other DIR-8xx A1 models. Existing DIR-882 A1 openwrt
"factory" firmware installs without modificaitons via the D-Link
Recovery GUI and has no known incompatibilities with the DIR-1935 A1.

Changes to be committed:
       new file:   target/linux/ramips/dts/mt7621_dlink_dir-1935-a1.dts
       modified:   target/linux/ramips/image/mt7621.mk
       modified:   target/linux/ramips/mt7621/base-files/etc/board.d/01_leds

Specifications:
* Board: Not known
* SoC: MediaTek MT7621 Family
* RAM: 128 MB (DDR3)
* Flash: 16 MB (SPI NOR)
* WiFi: MediaTek MT7615 Family (x2)
* Switch: 1 WAN, 4 LAN (Gigabit)
* Ports: 1 USB 3.0
* Buttons: Reset, WiFi Toggle, WPS
* LEDs: Power (green/orange), Internet (green/orange), WiFi 2.4G (green),
        WiFi 5G (green)

Notes:
* 160MHz 5GHz is available in LuCi but does not appear to work (i.e. no
  SSID is visible in wifi scanning apps on other devices) with either
  official DIR-882 A1 firmware or a test build for the DIR-1935 A1 based
  on the 22.03.2 branch. 80 MHz 5GHz works.

Serial port:
* Untested (potential user damage/error)
* Expected to be identical to other DIR-8xx A1 models:
	* Parameters: 57600, 8N1
	* Location: J1 header (close to the Reset, WiFi and WPS buttons)
	* Pinout: 1 - VCC
		  2 - RXD
	          3 - TXD
		  4 - GND

Installation:
* D-Link Recovery GUI: power down the router, press and hold the reset
  button, then re-plug it. Keep the reset button pressed until the power
  LED starts flashing orange, manually assign a static IP address under
  the 192.168.0.xxx subnet (e.g. 192.168.0.2) and go to http://192.168.0.1

* Some modern browsers may have problems flashing via the Recovery GUI,
  if that occurs consider uploading the firmware through cURL:

    curl -v -i -F "firmware=@file.bin" 192.168.0.1

Notes
-----
[1] WAN MAC address:
   a. First octet of WAN MAC is differ than others and OUI is not related
      to TP-Link company. This probably should be fixed.
   b. Flipping bits in first octet and hex delta are different for the
      different MAC examples:
      +-----------------+----------------+----------------+
      |                 | Example 1      | Example 2      |
      +-----------------+----------------+----------------+
      | LAN             | 68 = 0110 1000 | 50 = 0101 0000 |
      | MAC (1st octet) |         ^ ^ ^  |                |
      +-----------------+----------------+----------------+
      | WAN             | 72 = 0111 0010 | 54 = 0101 0100 |
      | MAC (1st octet) |         ^ ^ ^  |            ^   |
      +-----------------+----------------+----------------+
      | HEX delta       | 0xa            | 0x4            |
      +-----------------+----------------+----------------+
      | DEC delta       | 4              | 4              |
      +-----------------+----------------+----------------+
   c. DEC delta is a constant (4). This looks like a mistake in OEM
      firmware and probably should be fixed.
   Based on the above, I decided to keep correct OUI and make WAN MAC =
   label + 1.

[2] Bootloaders
   The device contains 3 bootloaders:
   - First U-Boot: U-Boot 1.1.3 (Mar 18 2019 - 12:50:24). The First U-Boot
     located on NAND Flash to load next full-feature Uboot.
   - Main U-Boot + its backup: U-Boot 1.1.3 (Mar 18 2019 - 12:50:29). This
     bootloader includes recovery webserver. Requires special uImages to
     continue the boot process:
        0x00 (os0, os1) - firmware uImage
        0x40 (os0, os1) - standalone uImage (OpenWrt kernel is here)
   - Additionally, both slots of the original TP-Link firmware contains
     Image U-Boot: U-Boot 1.1.3 (Oct 16 2019 - 08:14:45). It checks image
     magics and CRCs. We don't use this U-Boot with OpenWrt.
