Upstream uses a different filename, so lets rename our downstream
mt7981.dtsi to mt7981b.dtsi and update the device tree of all
MT7981 boards accordingly.
This is to prepare for the switch to Linux 6.12 which is going to
use the upstream mt7981b.dtsi (plus some patches on top).

Installation
-----------------------------------------------------------
Vendor-UI Method
-----------------------------------------------------------
1. Download the OpenWrt initramfs.trx image.
2. Connect the PC via LAN to one of the yellow router ports and wait
until your PC to get a DHCP lease.
3. Browse to http://192.168.50.1
4. If your router is brand new, finish the setup process and log into
the Web-UI.
5. Navigate to Administration -> Firmware Upgrade and upload the
downloaded OpenWrt image.
6. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device
using scp and install using sysupgrade.
$ sysupgrade -n <path-to-sysupgrade.bin>
-----------------------------------------------------------
TFTP Method
-----------------------------------------------------------
1. Download the OpenWrt initramfs image. Copy the image to a TFTP server
reachable at 192.168.1.70/24. Rename the image to rtax52.bin.
2. Connect the PC with TFTP server to the RT-AX52.
Set a static ip on the ethernet interface of your PC.
(ip address: 192.168.1.70, subnet mask:255.255.255.0)
Conect to the serial console,
interrupt the autoboot process by pressing '4' when prompted.
3. Download & Boot the OpenWrt initramfs image.
$ setenv ipaddr 192.168.1.1
$ setenv serverip 192.168.1.70
$ tftpboot 0x46000000 rtax52.bin
$ bootm 0x46000000
4. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device
using scp and install using sysupgrade.
$ sysupgrade -n <path-to-sysupgrade.bin>
---------------------------------------------------------------------------
Revert to stock firmware:
1: Download the rt-ax52 firmware from ASUS official website. Save
the firmware to tftp server directory and rename to RT-AX52.trx
2: Connect the PC with TFTP server to the RT-AX52.
Set a static ip on the ethernet interface of your PC.
(ip address: 192.168.1.70, subnet mask:255.255.255.0)
3: Conect to the serial console, power on again, interrupt the
autoboot process by pressing '4' when prompted.
$: ubi remove linux
$: ubi remove jffs2
$: ubi remove rootfs
$: ubi remove rootfs_data
$: ubi create linux 0x45fe000
$: reset
Then the dut will reboot,interrupt the autoboot process by
pressing '2' when prompted.
2: Load System code then write to Flash via TFTP.
Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N)
$: enter y
you will see the follow, type enter directly:
Input device IP (192.168.1.1) ==:
Input server IP (192.168.1.70) ==:
Input Linux Kernel filename (RT-AX52.trx) ==:
4: wait for the device run up
