ramips: add support for Buffalo WSR-2533DHPL Buffalo WSR-2533DHPL is a 2.4/5 GHz band 11ac router, based on MediaTek MT7621A. Specification: - SoC : MediaTek MT7621A - RAM : DDR3 128 MiB - Flash : SPI-NOR 16 MiB - WLAN : 2.4/5 GHz 4T4R (2x MediaTek MT7615N) - Ethernet : 10/100/1000 Mbps - Switch : MediaTek MT7530 (SoC) - LED/keys : 8x/6x (3x buttons, 2x slide-switches) - UART : through-hole on PCB - J4: 3.3V, GND, TX, RX from triangle-mark - 57600n8 - Power : 12VDC 1.5A Flash instruction using initramfs image: 1. prepare the TFTP server with the initramfs image renamed to "linux.trx-recovery" and IP address "192.168.11.2" 2. press the "AOSS" button while powering on the WSR-2533DHPL 3. after 10 seconds, release the "AOSS" button, WSR-2533DHPL downloads the initramfs image and boot with it automatically 4. on the initramfs image, download the sysupgrade image to the device and perform sysupgrade with it 5. wait ~120 seconds to complete flashing Switch position overview: - slide-switch1 (2x positions) - "AUTO" - "MANUAL" (not connected to gpio) - slide-switch2 (3x positions) - "ROUTER" - "AP" (not connected to gpio) - "WB"
