ath79: add support for ubnt_bullet-m-ar7240 variant
This adds support for the Ubiquiti Bullet M (AR7240). Specifications: - AR7240 SoC @ 400 MHz - 32 MB RAM - 8 MB SPI flash - 1x 10/100 Mbps Ethernet, 24 Vdc PoE-in - External antenna - POWER/LAN green LEDs - 4x RSSI LEDs (red, orange, green, green) - UART (115200 8N1) on PCB Flashing via WebUI: Upload the factory image via the stock firmware web UI. Attention: airOS firmware versions >= 5.6 have a new bootloader with an incompatible partition table! Please downgrade to <= 5.5 _before_ flashing OpenWrt! Refer to the device's Wiki page for further information. Flashing via TFTP: Same procedure as other Ubiquiti M boards. - Use a pointy tool (e.g., pen cap, paper clip) and keep the reset button on the device or on the PoE supply pressed - Power on the device via PoE (keep reset button pressed) - Keep pressing until LEDs flash alternatively LED1+LED3 => LED2+LED4 => LED1+LED3, etc. - Release reset button - The device starts a TFTP server at 192.168.1.20 - Set a static IP on the computer (e.g., 192.168.1.21/24) - Upload via tftp the factory image: $ tftp 192.168.1.20 tftp> bin tftp> trace tftp> put openwrt-ath79-generic-xxxxx-ubnt_bullet-m-ar7240-squashfs-factory.bin The "fixed-link" section of the device tree is needed to avoid errors like this: Generic PHY mdio.0:1f:04: Master/Slave resolution failed, maybe conflicting manual settings? With "fixed-link", the errors go away and eth0 comes up reliably.
