mediatek: add support for YunCore AX835
Hardware specification:
SoC: MediaTek MT7981B 2x A53
Flash: 16MB NOR
RAM: 256MB
Ethernet: 2x 10/100/1000 Mbps
Switch: MediaTek MT7531AE
WiFi: MediaTek MT7976C
Button: Reset
Power: DC 12V 1A, PoE 802.3af 48V
Flash instructions:
Option #1 - SSH
I was able to SSH into the stock firmware of my device.
1. Attach the router to the network
2. Use scp (-O) to copy the sysupgrade image
3. Connect using SSH and run `sysupgrade -n`
Option #2 - U-Boot
One way to use the bootloader for flashing is using TFTP:
1. Connect to the router using an ethernet cable
2 Spin up a TFTP server serving the sysupgrade file
3. Open the case and attach a UART
4. Attach power to the router and interrupt the countdown by pressing
any key
5. Select option #2 (Upgrade firmware)
6. Enter IP address information and image name
7. Wait patiently
