ar71xx: add support for ALFA Network R36A
ALFA Network R36A is a successor of the previous model, the R36 (Ralink RT3050F based). New version is based on Qualcomm/Atheros QCA9531 v2. Specification: - 650/400/200 MHz (CPU/DDR/AHB) - 64 MB of RAM (DDR2) - 16 MB of FLASH (SPI NOR) - 2x 10/100 Mbps Ethernet, with passive PoE support (24 V) - 2T2R (QCA9531) 2.4 GHz, 2x u.fl connectors on PCB - 1x USB 2.0 (power controlled by GPIO) - 6x LED (5 of them are driven by GPIO) - 2x button (reset, wifi/wps) - external h/w watchdog (EM6324QYSP5B, disabled and not used) - DC jack for main power input (12 V) - UART header on PCB Flash instruction: You can use sysupgrade image directly in vendor firmware which is based on LEDE/OpenWrt. Alternatively, you can use web recovery mode in U-Boot: 1. Configure PC with static IP 192.168.1.2/24. 2. Connect PC with one of RJ45 ports, press the reset button, power up device, wait for first blink of all LEDs (indicates network setup), then keep button for 3 following blinks and release it. 3. Open 192.168.1.1 address in your browser and upload sysupgrade image. Signed-off-by: Piotr Dymacz <pepe2k@gmail.com>
