ramips: add support for I-O DATA WN-GX300GR
I-O DATA WN-GX300GR is a 2.4 GHz band 11n router, based on MediaTek MT7621S. Specification: - MT7621S (1-Core, 2-Threads) - 64 MB of RAM - 8 MB of Flash (SPI) - 2T2R 2.4 GHz - 5x 10/100/1000 Mbps Ethernet - 2x LEDs, 4x keys (2x buttons, 1x slide switch) - UART header on PCB - Vcc, GND, TX, RX from ethernet port side - baudrate: 115200 bps (U-Boot, OpenWrt) Flash instruction using initramfs image: 1. Connect serial cable to UART header 2. Rename OpenWrt initramfs image for WN-GX300GR to "uImageWN-GX300GR" and place it in the TFTP directory 3. Set the IP address of the computer to 192.168.99.8, connect to the LAN port of WN-GX300GR, and start the TFTP server on the computer 4. Connect power cable to WN-GX300GR and turn on the router 5. Press "1" key on the serial console to interrupt boot process on U-Boot, press Enter key 3 times and start firmware download via TFTP 6. WN-GX300GR downloads initramfs image and boot with it 7. On the initramfs image, execute "mtd erase firmware" to erase stock firmware and execute sysupgrade with sysupgrade image for WN-GX300GR 8. Wait ~150 seconds to complete flasing Signed-off-by: INAGAKI Hiroshi <musashino.open@gmail.com>
