ramips: add support for TP-Link TL-WR902AC v3
TP-Link TL-WR902AC v3 is a pocket-size dual-band (AC750) router based on MediaTek MT7628N + MT7650E. Specification: - MediaTek MT7628N/N (580 Mhz) - 64 MB of RAM - 8 MB of FLASH - 2T2R 2.4 GHz and 1T1R 5 GHz - 1x 10/100 Mbps Ethernet * MT7650 ac chip isn't not supported by LEDE/OpenWrt at the moment. Therefore 5Ghz won' work. Flash instruction: The only way to flash LEDE image in TL-WR902AC v3 is to use tftp recovery mode in U-Boot: 1. Configure PC with static IP 192.168.0.66/24 and tftp server. 2. Rename "openwrt-ramips-mt76x8-tplink_tl-wr902ac-v3-squashfs-tftp-recovery.bin" to "tp_recovery.bin" and place it in tftp server directory. 3. Connect PC with the LAN port, press the reset button, power up the router and keep button pressed for around 6-7 seconds, until device starts downloading the file. 4. Router will download file from server, write it to flash and reboot.
