ramips: add support for TP-Link Deco M4R v4 This commit adds support for the V4 hardware revision of the Deco M4R. V4 is a complete overhaul of the hardware compared to V1 and V2, and is much more similar to the Archer C6 V3 and C6U V1. Specifications: SoC: MediaTek MT7621AT (2 cores at 880 MHz, 4 threads) RAM: Kingston D1216ECMDXGJD (256 MB) Wireless 2.4 GHz: MediaTek MT7603EN Wireless 5 GHz: MediaTek MT7613BEN Flash: 16 MB SPI NOR Installation: Flash the *-factory.bin image in the U-Boot recovery webserver. You can trigger this webserver by holding the reset button until the LED flashes yellow, or by hooking up to serial pads on the board (clearly labeled GND, RX and TX) and pressing `x` early in boot. Once the factory image has been flashed, you can use the regular upgrade procedure with sysupgrade images for subsequent flashes.
