ramips: add xiaomi_miwifi-r3 support
Specification: - CPU: 580 MHz - Flash size: 128 MiB NAND - RAM size: 128 MiB DDR2 - Wireless No1: SoC-integrated: MT7620A 2x2 MIMO 802.11b/g/n (2.4 GHz) - Wireless No2: On-board chip: MT7612E 2x2 MIMO 802.11a/n/ac (5 GHz) - Switch: MT7620 built-in 10/100 switch w/ vlan support - USB: 2.0 x1 Flash instructions: 1. access ssh via https://wiki.openwrt.org/toh/xiaomi/mir3 2. in ssh: nvram set flag_last_success=1 nvram set boot_wait=on nvram set uart_en=1 nvram commit mtd write lede-ramips-mt7620-miwifi-r3-squashfs-kernel1.bin kernel1 mtd write lede-ramips-mt7620-miwifi-r3-squashfs-rootfs0.bin rootfs0 reboot If you want to revert back to stock fw while on LEDE: insert usb stick (FAT/FAT32) with stock fw renamed to miwifi.bin fw_setenv flag_last_success 0 power off the device hold the reset button and power on the device, keep holding the reset button until yellow led starts blinking.
