ramips: add support for ALFA Network AC1200RM
ALFA Network AC1200RM is an AC1200 router, with 5-port FE switch and USB 2.0 port. Device is based on MediaTek MT7620A + MT7612EN. Specification: - MT7620A (580 MHz) - 64 MB of RAM (DDR2) - 16 MB of FLASH (SPI NOR) - 5x 10/100 Mbps Ethernet with passive PoE output in WAN and LAN4 - 2T2R 2.4 GHz (MT7620A) - 2T2R 5 GHz (MT7612EN) - 1x USB 2.0 - 9x LED (8 driven by GPIO) - 1x button (reset) - DC jack for main power input (12-24 V) - 2x UART, I2C, I2S and LED headers Flash instruction (do it under U-Boot, using UART and TFTP server): Select option "2: Load system code then write to Flash via TFTP" and use "sysupgrade" image.
