Subject: [PATCH] mediatek: add support for GL.iNet GL-MT2500

Hardware
--------
SoC:  MediaTek MT7981BA
RAM:  1GB DDR4 (NANYA NT5AD512M16C4-JR)
MMC:  8GB eMMC (Samsung 8GTF4R)
ETH:  1000Base-T LAN (ePHY)
      2500Base-T WAN (MaxLinear GPY211C)
BTN:  1x Reset Button
LED:  System (blue/white)
      VPN (white)
USB:  1x USB-A (USB 3.0)
UART: 115200 8N1 - Pinout on board next to LAN port
      Don't connect 3.3V!

Known Issues
------------
U-Boot vendor recovery does not seem to accept any images, neither
GL.iNet images nor OpenWrt images. Recovery requires serial access!

Installation
------------
Upload the OpenWrt sysupgrade image to the Gl.iNet Web-UI. Make sure to
not retain existing settings.
