ramips: add support for ASUS RT-N56U B1
Specifications: SoC: MediaTek MT7621ST (880 MHz) FLASH: 16 MiB (Macronix MX25L12835FM2I-10G) RAM: 128 MiB (Nanya NT5CB64M16FP-DH) WiFi: MediaTek MT7603EN bgn 2x2:2 WiFi: MediaTek MT7612EN an 2x2:2 BTN: Reset, WPS LED: - Power - WiFi 2.4 GHz - WiFi 5 GHz - WAN - LAN {1-4} - USB {1-2} UART: UART is present as pin hole next to the aluminium capacitor. 3V3 - RX - GND - TX / 115200-8N1 3V3 is the nearest on the aluminium capacitor and nut hole (pin1). USB: 2 ports POWER: 12VDC, 1.5A (Barrel 5.5x2.1) Installation: Via TFTP: Set your computers IP-Address to 192.168.1.75 Power up the Router with the Reset button pressed. Release the Reset button after 5 seconds. Upload OpenWRT sysupgrade image via TFTP: tftp -4 -v -m binary 192.168.1.1 -c put IMAGE MAC addresses: 0x4 *:98 2g/wan, label 0x22 *:9c 0x28 *:98 0x8004 *:9c 5g/lan Though addresses are written to 0x22 and 0x28, it appears that the vendor firmware actually only uses 0x4 and 0x8004. Thus, we do the same here.
