485f9b0d31 ramips: add support for D-Link DIR-2660 A2
This patch adds support for D-Link DIR-2660 A2.
Based on the commit: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=b5dd746cbb1aaf91f4b68e9f3eda97413550d904,

Both devices look identical, except for the A1/A2 designation.
You can safely install the A1 firmware for the A2 – I've been testing it for several months as a DUMB AP – without any problems.

Specifications:
* SoC: MediaTek MT7621AT
* RAM: 256 MB (DDR3)
* Flash: 128 MB (NAND)
* WiFi: MediaTek MT7615N (x2)
* Switch: 1 WAN, 4 LAN (Gigabit)
* Ports: 1 USB 2.0, 1 USB 3.0
* Buttons: Reset, WPS
* LEDs: Power (white/orange), Internet (white/orange), WiFi 2.4G (white),
        WiFi 5G (white), USB 3.0 (white), USB 2.0 (white)

Notes:
* WiFi 2.4G and WiFi 5G LEDs are wired directly to the wireless chips

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

2cce634a9e ramips: disable build TP-Link EAP235-Wall
Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
After investigating the EAP235-Wall u-boot GPL code, it was found that
the u-boot of this device directly loads the kernel from the SPI NOR
Flash direct access address. However, due to hardware limitation, MT7621
can only remap the first 4MiB Flash. Excluding some partitions before
the kernel, this device can only boot kernels smaller than 0x360000.
This means that unless you install a modified bootloader, the mainline
OpenWrt will no longer work on this model.

97256a28fe ramips: add support for EDUP EP-RT2960S
Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
Build all core packages / Build all core packages for selected target (push) Waiting to run
EDUP EP-RT2960S has the similar hardware design as the SIMAX1800T.
The main difference is the arrangement of the GPIO pins
and the location of the MAC address.

Specification
-------------
- SoC       : Mediatek MT7621
- RAM       : 256 MiB DDR3
- Flash     : 128 MiB NAND Flash
- WLAN      : Mediatek MT7905 DBDC
  - 2.4 GHz : 2x2 MIMO WiFi6
  - 5 GHz   : 2x2 MIMO WiFi6
- Ethernet  : MT7621 built-in 10/100/1000 Mbps 1x WAN; 3x LAN
- UART      : 3.3V, 115200n8
- Buttons   : 1x RESET; 1x WPS/MESH
- LEDs      : 1x Multi-Color(Blue;Green;Red)
- Power     : DC 12V1A
- CMIIT ID  : 2022AP7163
- TFTP IP   :
  - server  : 192.168.1.254
  - router  : 192.168.1.28

TFTP Installation(recommend)
------------
1. Set local tftp server IP "192.168.1.254" and NetMask "255.255.255.0".
2. Rename initramfs-kernel.bin to "factory.bin" and put it in the root
   directory of the tftp server. tftpd64 is a good choice for Windows.
3. Remove all Ethernet cables and WiFi connections from the PC, except
   for the one connected to the EDUP EP-RT2960S. Start the TFTP server, plug
   in the power adapter and wait for the OpenWrt system to boot.
4. Backup "firmware" partition and rename it to "firmware.bin". We need
   it to back to the stock firmware.
5. Use "fw_printenv" command to list envs. If "firmware_select=2" is
   observed then set u-boot env variable via command:
   `fw_setenv firmware_select 1`
6. Apply sysupgrade.bin in OpenWrt LuCI.

Web UI Installation
------------
1. Apply update by uploading initramfs-factory.bin to the web UI.
2. Use "fw_printenv" command to list envs. If "firmware_select=2" is
   observed then set u-boot env variable via command:
   `fw_setenv firmware_select 1`
3. Apply squashfs-sysupgrade.bin in OpenWrt LuCI.

Return to Stock Firmware
----------------------------
  Restore the backup firmware partition in the installation step 4.

35a86267e9 ramips: fix support for Cudy r700
This PR fixes support for Cudy r700.

Original PR: https://github.com/openwrt/openwrt/pull/18532
Fixed:

- WAN port functionality;
- RESET button;
- Status LED;
- LAN port names consistent with the chassis;
- Merged partitions "debug", "backup" & "firmware"  to one partition "firmware" ("debug" & "backup" contained unimportant data);
- Removed redundant DTS elements.

Installation:

To install OpenWRT, you need the intermediate firmware from Cudy. (U-boot is locked). After installing the intermediate firmware, you can install OpenWRT via sysupgrade.

Recovery:

TFTP available.
1. Place the recovery.bin in the serving directory of your TFTP server.
2. Set your IP to 192.168.1.88/24.
3. Press the “Reset” button of Cudy router and hold it. Before the Cudy router is powered on and before TFTP start to download the firmware, don't release the “Reset” button.
4. Power on the Cudy router.
5. You can release the reset button only when TFTP starts downloading firmware.
6. When the SYSTEM LED turns solid green, the upgrade is complete.

Installation:
The factory firmware is locked: you can only work with Cudy signed firmware.
Download a intermediate firmware signed by Cudy here:
https://www.cudy.com/blogs/faq/openwrt-software-download

After that, login to the router (192.168.10.254, password "admin") and install the intermediate firmware.

If you can reach LuCI or SSH now on the intermediate firmware, just use the sysupgrade image with the 'Keep settings' option turned off.

Special thanks to Daniel de Kock for starting the porting work at #16265.

Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
Both devices seem to be completely identical and D-Link doesnt even
mention the DIR-X1550 A1 in the GPL source. Furthermore the supported
devices header also just contains DIR-X1860 B1. The cherry on top is the
FCC filing, which features the manual for DIR-X1550 A1 but the label
info for DIR-X1860 B1. I guess someone at D-Link was just as confused as
me.

4193422377 ramips: add support for Zyxel NWA90AX access point
The NWA90AX is hardware-wise identical to the NWA50AX which is
already supported.

The NWA90AX magic model code bytes are `77 E1`,
and they are added to the DTS to mark the NWA50AX firmware
as being compatible with the 90 model.

Without the compat-models change, uploading the OpenWrt NWA50AX
firmware with the official Zyxel web interface yields an error:
> errno: -25007
> errmsg: Firmware content error!

As described on the NWA50AX firmware page[1] on the wiki, the
"current image" slot for firmware updates has to be "1".
If it is 0, flashing will fail.

f6e0f57be0 targetwide: imagebuilder: add explicit guards around initramfs rules
Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
The imagebuilder is not intended to build initramfs images.  Some
profiles attempt to do this and succeed, due to buildroot leaking
the initramfs-kernel into staging_dir; others attempt it, but fail
due to not having initramfs binaries present in the imagebuilder.

Fix this by adding an explict guard around the unsupported generation
of the initramfs images.  This saves space and time during imagebuilder
runs, fixes those that are currently broken and protects against future
breakage for profiles that inadvertently work now.

Flashing instructions:
======================

Various methods can be used to install the actual image on the flash.
Two easy ones are:

ap51-flash
----------

The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the image to the u-boot when the device boots up.

initramfs from TFTP
-------------------

The serial console (115200 8N1) must be used to access the u-boot shell
during bootup. It can then be used to first boot up the initramfs image
from a TFTP server (here with the IP 192.168.1.21):

    setenv serverip 192.168.1.21
    setenv ipaddr 192.168.1.1
    tftpboot 0x83001000 <filename-of-initramfs-kernel>.bin && bootm $fileaddr

The actual sysupgrade image can then be transferred (on the LAN port) to the
device via

    scp <filename-of-squashfs-sysupgrade>.bin root@192.168.1.1:/tmp/

On the device, the sysupgrade must then be started using

    sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin

SIM SIMAX1800U has the similar hardware design as the SIMAX1800T. The
only difference is the Ethernet portmap.

Specification
-------------
- SoC       : Mediatek MT7621
- RAM       : 256 MiB DDR3
- Flash     : 128 MiB NAND Flash
- WLAN      : Mediatek MT7905 DBDC

- TFTP IP   :
  - server  : 192.168.1.254
  - router  : 192.168.1.28

TFTP Installation(recommend)
------------
1. Set local tftp server IP "192.168.1.254" and NetMask "255.255.255.0".
2. Rename initramfs-kernel.bin to "factory.bin" and put it in the root
   directory of the tftp server. tftpd64 is a good choice for Windows.
3. Remove all Ethernet cables and WiFi connections from the PC, except
   for the one connected to the SIMAX1800U. Start the TFTP server, plug
   in the power adapter and wait for the OpenWrt system to boot.
4. Backup "firmware" partition and rename it to "firmware.bin". We need
   it to back to the stock firmware.
5. Use "fw_printenv" command to list envs. If "firmware_select=2" is
   observed then set u-boot env variable via command:
   `fw_setenv firmware_select 1`
6. Apply sysupgrade.bin in OpenWrt LuCI.

Web UI Installation
------------
1. Apply update by uploading initramfs-factory.bin to the web UI.
2. Use "fw_printenv" command to list envs. If "firmware_select=2" is
   observed then set u-boot env variable via command:
   `fw_setenv firmware_select 1`
3. Apply squashfs-sysupgrade.bin in OpenWrt LuCI.

Return to Stock Firmware
----------------------------
  Restore the backup firmware partition in the installation step 4.

28a88ff7e6 ramips: EAP615-Wall v1: fix bootloop by reducing LZMA dictionary
Fix bootloop on TP-Link EAP615-Wall v1 by reducing LZMA dictionary
size. Before this patch and after an upgrade to kernel 6.12 this
device couldn't boot a kernel because of an error: "lzma compressed:
uncompress error 1".

I have chosen -d22 as dictionary size as suggested by @namiltd.
The usual sizes for problematic devices are -d16, -d20, -d22. I
have confirmed with my tests that this device can boot with a value
up to -d27, but there is no size benefit from values above -d21,
therefore -d22 is good enough.

dd15117dab ramips: add support for TP-Link EX220 v2
This device is similar to the TP-Link EX220 v1.
The differences are the number of ports (3 LANs
and 1 WAN) and the number of LEDs (1 LED RGB)

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
        LED - (TX - RX - GND - 3V3 ) - 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 the LED 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.

c35f2a23c8 ramips: mt7621: add support for JDCloud RE-SP-01B
JDCloud RE-SP-01B is a dual-band WiFi 5 router based on the MT7621AT.

Specifications:
- SoC: MediaTek MT7621AT
- RAM: 512MB DDR3
- Flash: 32MB SPI NOR
- WiFi: MediaTek MT7603EN (2.4GHz), MediaTek MT7615N (5GHz)
- Ethernet: 1x WAN, 2x LAN (Gigabit Ethernet)
- LEDs: red, blue, green (GPIO controlled)
- Button: Reset (GPIO controlled)
- eMMC: Single onboard (32GB/64GB/128GB)
- USB: 1x USB 2.0 port

MAC Address Structure:
The MAC addresses share the structure DC:D8:7C:XX:XX:XX, where:
- WAN, LAN, and 2.4GHz WiFi: same as the label MAC address.
- 5GHz WiFi: label MAC address + 0x800000.

The manufacturer writes the label MAC address at different
offsets depending on the storage version of the device:

e.g.
128GB version:  &config + 0x442a
64GB version:   &config + 0x4429

So `get_mac_ascii()` is used here to search for the
base label MAC address of the device.

Ref:
https://github.com/openwrt/openwrt/pull/17409#discussion_r1899674262
https://github.com/immortalwrt/immortalwrt/commit/c0c480d

Flash Instruction:
A 3rd party bootloader is required to boot the image. You can
use a SOP16 test clip to burn the image/bootloader to the flash.

The official bootloader does provide a web recovery interface
which only accepts an official image. To access it, you will
need to hold the reset button and power on the device, set your
IP address to 192.168.68.2 and visit http://192.168.68.1.

b6a07dd091 ramips: mt7621: add support for Arcadyan WE410443
The Arcadyan WE410443 is a WiFi AC access point distributed by various ISPs
under various names, including KPN SuperWifi and BT Whole Home Wi-Fi. It
features one ethernet port, dual MT7615N radios and four internal antennas.

Hardware:
- SoC: Mediatek MT7621AT
- Flash: 32 MB
- RAM: 128 MB
- Ethernet: 1x 10/100/1000 Mbps, built into the SoC
- WLAN: 2x MediaTek MT7615N
- Buttons: 1 Reset button, 1 WPS button
- LEDs: 1x Green, 1x Blue, 1x Red, all unmarked
- Power: 12 VDC, 1.5A barrel plug

Installation:
The bootloader is locked with a password, so the image needs to be written
directly to the SPI flash chip. To do this, you need to open up the case,
remove the heatsink and connect the flash chip to a Raspberry Pi. Use the
following connections:

Flash chip --> Raspberry Pi

VCC --> 3v3
RESET --> 3v3
/CS --> GPIO 8
DO --> GPIO 9
CLK --> GPIO 11
DI --> GPIO 10
GND --> Ground

You can solder wires to the flash chip, or use a SOIC16 clip. More details on
the Raspberry Pi and SPI chip pinouts are available on the wiki [1]
When you have the Raspberry Pi connected to the flash chip, boot your Pi and
follow the instructions:

1) Make sure your Pi has SPI enabled with sudo raspi-config

2) Install necessary tools: sudo apt install xxd libubootenv-tool mtd-utils

3) Upload overlay and execute:
sudo dtc -@ -I dts -O dtb -o
/boot/overlays/we410443.dtbo we410443-overlay.dts

4) Enable in /boot/firmware/config.txt by adding a new line containing
dtoverlay=we410443

5) Reboot your Pi and verify the mtd partitions with
cat /proc/mtd, you should see:

dev:    size   erasesize  name
mtd0: 02000000 00001000 "all"
mtd1: 00030000 00001000 "u-boot"
mtd2: 00010000 00001000 "u-boot-env"
mtd3: 00010000 00001000 "factory"
mtd4: 01f60000 00001000 "firmware"
mtd5: 00010000 00001000 "glbcfg"
mtd6: 00010000 00001000 "config"
mtd7: 00010000 00001000 "glbcfg2"
mtd8: 00010000 00001000 "config2"

6) Optionally (but recommended), make a backup:
sudo dd if=/dev/mtd0 of=backup.bin
It can be restored with: sudo flashcp backup.bin /dev/mtd0

7) Set the variables for the bootloader:
echo '/dev/mtd2 0x0 0x1000 0x1000' > fw_env.config
sudo fw_setenv -c fw_env.config bootpartition 0

8) Finally, flash the image:
sudo flashcp openwrt-ramips-mt7621-arcadyan_we410443-
squashfs-sysupgrade.bin /dev/mtd4

MAC addresses
The label address is stored in ASCII in the config partition

Use --> Address

Device --> label
Ethernet --> label
WLAN 2g --> + 1
WLAN 5g --> + 2

RAM: 128 MiB
Ethernet: 5x Gbit ports

Installation:
There are two known options:

The Luci-based UI.
Press and hold the reset button during power up.
The router will request 'recovery.bin' from a TFTP server at
192.168.1.88.

Both options require a signed firmware binary.
A signed firmware can be found in GitHub PR #18532.

R4 & R5 need to be shorted (0-100Ω) for the UART to work.

Installation:

Update Mofi 5500 to at least stock firmware version 4.8.6. (Available on the Mofi website.)
Previous versions are untested in the upgrade process. Log into the LuCI web interface,
usually at 192.168.10.1 and visit the 'System->Backup/Flash Firmware' page.
Upload and flash the firmware as usual.

Note to Maintainers: Do not remove SUPPORTED_DEVICES from the Makefile!
The customized Mofi version of OpenWRT (stock firmware) expects to see mofi5500 as the device
name. The stock firmware does not allow for forcing an installation.
Without this line, users cannot upload the new firmware through the stock Mofi firmware.

This device uses cell modems that could use QMI or MBIM.
Add LuCI Modem Manager to allow people to use these. Also, if they have
two cell network cards, ethernet, USB, or other kinds of networks, they may wish
to use MWAN3 to allow failover amongst their networks.

Please compile it with mwan3 for multiple WAN connections.

3e7337feea ramips: Add support for Genexis / Inteno Pulse EX400
Add support for Genexis Pulse EX400 / Inteno Pulse EX400. A branded
variant for the Finnish ISP DNA has already been added in fea2264d9f
(ramips: mt7621: Add DNA Valokuitu Plus EX400, 2023-07-31). This commit
adds support for the generic variants with Inteno and Genexis branding.
Inteno changed its name to Genexis and both brandings exist.

In terms of electronics, there is no difference between the DNA-branded
version and other brandings. LED markings on the case are different,
though. While the DNA-version has a "software-update" LED, the other
versions have a WPS LED. To reduce user confusion, create a separate
image.

Add the different device-tree with the different LED and rename things
to work the same way for both variants.

Specifications:
- Device: Genexis Pulse EX400 / Inteno Pulse EX400
- SoC: MT7621A
- Flash: 256 MB NAND
- RAM: 256 MB
- Ethernet: Built-in, 2 x 1 GbE
- Wifi: MT7603 2.4 GHz 2x2 MIMO, MT7615 5 GHz 4x4 MU-MIMO
- USB: 1x 2.0
- LEDs (GPIO): green/red status, green WPS
- LEDs (SX9512, unsupported): Broadband, Wi-Fi 2.4G, Wi-Fi 5G
- Buttons (GPIO): Reset
- Buttons (SX9512, unsupported): Wi-Fi 2.4G, Wi-Fi 5G, WPS

MAC addresses:
- LAN:     U-Boot 'ethaddr' (label)
- WAN:     label + 1
- 2.4 GHz: label + 6
- 5 GHz:   label + 7

Serial:
 There is a black block connector next to the red ethernet connector. It
 is accessible also through holes in the casing.

Firmware:
 The vendor firmware is a fork of OpenWrt (Reboot) with a kernel version
 4.4.93. The flash is arranged as below and there is a dual boot
 mechanism alternating between rootfs_0 and rootfs_1.

 +-------+------+------+-----------+-----------+
 |       | env1 | env2 | rootfs_0  |  rootfs_1 |
 |       +------+------+-----------+-----------+
 |       |         UBI volumes                 |
 +-------+-------------------------------------+
 |U-Boot |             UBI                     |
 +-------+-------------------------------------+
 |mtd0   |             mtd1                    |
 +-------+-------------------------------------+
 |                     NAND                    |
 +---------------------------------------------+

 In OpenWrt rootfs_0 will be used as a boot partition that will contain the
 kernel and the dtb. The squashfs rootfs and overlay are standard OpenWrt
 behaviour.

 +-------+------+------+-----------+--------+------------+
 |       | env1 | env2 | rootfs_0  | rootfs | rootfs_data|
 |       +------+------+-----------+--------+------------+
 |       |         UBI volumes                           |

 +-------------------------------------------------------+

U-boot:
 With proper serial access, booting can be halted to U-boot by pressing
 any key. TFTP and flash writes are available, but only the first one has
 been tested.

 NOTE: Recovery mode can be accessed by holding down the reset button while
 powering on the device. The led 'Update' will show a solid green light
 once ready. A web server will be running at 192.168.1.1:80 and it will
 allow flashing a firmware package. You can cycle between rootfs_0 and
 rootfs_1 by pressing the reset button once.

Root password:
 With the vendor web UI create a backup of your settings and download the
 archive to your computer. Within the archive in the file
 /etc/shadow replace the password hash for root with that of a password you
 know. Restore the configuration with the vendor web UI and you will have
 changed the root password.

SSH access:
 You might need to enable the SSH service for LAN interface as by default
 it's enabled for WAN only.

Installing OpenWrt:
 With the vendor web UI, or from the U-Boot recovery UI, install the
 OpenWrt factory image. Alternatively, ssh to the device and use
 sysupgrade -n from cli.

 Finalize by installing the OpenWrt sysupgrade image to get a fully
 functioning system.

Reverting to the vendor firmware:

 Boot with OpenWrt initramfs image
  - Remove volumes rootfs_0, rootfs and rootfs_data and create vendor
    volumes.

    ubirmvol /dev/ubi0 -n 2
    ubirmvol /dev/ubi0 -n 3
    ubirmvol /dev/ubi0 -n 4
    ubimkvol /dev/ubi0 -N rootfs_0 -S 990
    ubimkvol /dev/ubi0 -N rootfs_1 -S 990

    Power off and enter to the U-boot recovery to install the vendor
    firmware.

- There are two LEDs: Red (GPIO 3) and White (GPIO 4)
- There are two buttons: Reset (GPIO 8) and WPS (GPIO 10)

Migration to OpenWrt:
- Download the migration image from the Cudy website (it should be available as soon as OpenWrt officially supports the device)
- The migration image is also available here until a image is provided by Cudy: https://github.com/RolandoMagico/openwrt-build/releases/tag/M1300_Build_20240222
- File: openwrt-ramips-mt7621-cudy_m1300-v2-squashfs-flash-signed.bin
- Connect computer to LAN (bottom connector) and flash the migration image via OEM web interface
- In the migration image, LAN and WAN are swapped. Computer must be connected to the other port after flashing
- OpenWrt is now accessible via 192.168.1.1
- After flashing an up to date OpenWrt image, LAN and WAN settings are again the same as in the OEM firmware
- So use the other connector again

Revert back to OEM firmware:
- Set up a TFTP server on IP 192.168.1.88 and connect to the LAN port (lower port)
- Provide the Cudy firmware as recovery.bin in the TFTP server
- Press the reset button while powering on the device
- Recovery process is started now
- When recovery process is done, OEM firmware is accessible via 192.168.10.1 again

General information:
- No possibility to load a initramfs image via U-Boot because there is no option to interrupt U-Boot

Disassembly:
There are 2 screws at the bottom. After removing the screws, pry the gray plastic part around (it is secured with latches) and remove it.

Serial Interface:
The serial interface can be connected to the 4 pin dots to the left of the radiator.
Pins (from LAN ports to LEDs):
3.3V (do not connect)
TX
RX
GND
Settings: 57600, 8N1

Flashing via OEM recovery software:
1. Download the OEM recovery software from the manufacturer's website
2. Download the firmware image (for OpenWRT it is *-squashfs-factory.bin), rename it to KN-1910_recovery.bin
3. Replace the file in the fw folder OEM recovery software with the file from step 2.
4. Run the OEM recovery software and follow the instructions.

Flashing via TFTP:
1. Connect your PC and router to port 1-4, configure PC interface using IP 192.168.1.2, mask 255.255.255.252
2. Serve the firmware image (for OpenWRT it is *-squashfs-factory.bin) renamed to KN-1910_recovery.bin via TFTP
3. Power up the router while pressing Reset button on the back
4. Release Restart button when Power LED starts blinking

To revert back to OEM firmware:
The return to the OEM firmware is carried out by using the methods described above with the help of the appropriate firmware image.

Keenetic's bootloader supports booting a LZMA compressed kernel but seems to fail if the uncompressed data is larger than a fixed buffer therefore it is safer to use a uimage-lzma-loader. When using OEM bootloader, the firmware image size cannot exceed the size of one OEM «Firmware_x» partition or Kernel + rootFS size.

ramips: mt7621: Edgerouter-X drop factory image
Edgerouter-X factory images have not built automatically since 19.x due
to images being over 3MB. While it was possible to build custom images
with very stripped down config, this is no longer possible with the size
increases of linux 6.1 and 6.6.

Drop code for generation of factory images, if some dev later wishes to
try custom images they can revert this commit.

With the new layout providing 6MB for kernel there will be no issues
with kernel size affecting build of images.

Re-enable image builds for Edgerouter-X and X-SFP.
