mediatek: add support for Mercusys MR80X v3
This commit adds support for Mercusys MR80X(EU) v3 router.
Device specification:
- SoC: Mediatek MT7981b, Cortex-A53, 64-bit
- RAM: 512MB
- Flash: SPI NAND GigaDevice GD5F1GQ5UEYIGY (128 MB)
- Ethernet: 4x 100/1000 Mbps LAN1,LAN2,LAN3 & WAN
- Wireless: 2.4GHz (802.11 b/g/n/ax)
- Wireless: 5GHz (802.11 a/n/ac/ax)
- LEDs: 1 orange and 1 green status LEDs, 4 green gpio-controlled LEDs
on ethernet ports
- Buttons: 1 (Reset)
- Bootloader: Main U-Boot - U-Boot 2022.01-rc4. Additionally, both UBI
slots contain "seconduboot" (also U-Boot 2022.01-rc4)
Installation (UART):
- Place OpenWrt sysupgrade image on tftp server with IP 192.168.1.2
- Attach UART, switch on the router and interrupt the boot process by
pressing 'Ctrl-C'.
- Upload the sysupgrade.bin via tftp.
setenv serverip 192.168.1.2; setenv ipaddr 192.168.1.1; tftp
0x40001000 sysupgrade.bin
- Erase "ubi0" part, and write the image.
nand erase.spread 0x300000 0x3200000; nand write.spread 0x40001000
0x300000 0x3200000
- Set the uboot environment for startup.
setenv tp_boot_idx 0; setenv bootcmd bootm 0x46000000; saveenv
- Reboot the router by reconnecting the power.
Recovery:
- Press Reset button and power on the router.
- Navigate to U-Boot recovery web server (http://192.168.1.1/) and
upload the OEM firmware.
