ath79: add support for Comfast CF-WR752AC v1
Specifications: - Qualcomm QCA9531 + QCA9886 - dual band, antenna 2*3dBi - Output power 50mW (17dBm) - 1x 10/100 Mbps LAN RJ45 - 128 MB RAM / 16 MB FLASH (w25q128) - 3 LEDs (red/green/blue) incorporated in "color wheel reset switch" - UART 115200 8N1 Flashing instructions: The U-boot bootloader contains a recovery HTTP server to upload the firmware. Push the reset button while powering the device on and keep it pressed for ~10 seconds. The device's LEDs will blink several times and the recovery page will be at http://192.168.1.1; use it to upload the sysupgrade image. Alternatively, the original firmware is based on OpenWrt so a sysupgrade image can be installed via the stock web GUI. Settings from the original firmware will be saved and restored on the new one, so a factory reset will be needed. To do so, once the new firmware is flashed, enter into failsafe mode by pressing the reset button several times during the boot process, until it starts flashing. Once in failsafe mode, perform a factory reset as usual. LED-Info: The LEDs on the Comfast stock fw have a very proprietary behaviour, corresponding to the user selected working mode (AP, ROUTER or REPEATER). In the first two cases, only blue is used for status and LAN signaling. When using the latter, blue is always off (except for sysupgrade), either red signals bad rssi on master-link, or green good. Since the default working mode of OpenWrt resembles that of a router/AP, the default behavior is implemented accordingly. MAC addresses (art partition): location address (example) use in vendor firmware 0x0 xx:xx:xx:xx:xc:f8 -> eth0 0x6 xx:xx:xx:xx:xc:fa -> wlan5g (+2) 0x1002 xx:xx:xx:xx:xc:f9 -> not used 0x5006 xx:xx:xx:xx:xc:fb -> not used --- xx:xx:xx:xx:xd:02 -> wlan2g (+10) The same strange situation has already been observed and documented for COMFAST CF-E560AC.
