Tianling Shen cc6c3a6ee8 mediatek: add support for OpenEmbed SOM7981
Hardware specification:
  SoC: MediaTek MT7981B 2x A53
  Flash: 256 MiB SPI-NAND, 32 GB eMMC optional
  RAM: 0.5/1 GB DDR4
  Ethernet: 1x 1GbE, 1x 2.5GbE (RTL8221B)
  WiFi: MediaTek MT7976C
  USB: 1x USB 3.0
  GPIO: 26-Pin header
  UART: 6 GND, 8 TX, 10 RX (in Pin header)
  Button: Reset, WPS
  Power: Type-C PD

Installation:
The board comes with a third-party custom OpenWrt image, you can upload
sysupgrade image via LuCI directly WITHOUT keeping configurations.

Or power on the board with pressing reset button for 5 second, then visit
http://192.168.1.1 and upload -factory.bin firmware.
