From: Pavel Balan <admin at kryma.net>

This patch adds support for the COMFAST CF-E130N v2, an outdoor wireless
CPE with a single Ethernet port and a 802.11bgn radio.

Specifications:

 - QCA9531 SoC
 - 1x 10/100 Mbps Ethernet with PoE-in support
 - 64 MB of RAM (DDR2)
 - 16 MB of FLASH
 - 5 dBi built-in antenna
 - POWER/LAN/WLAN green LEDs
 - 4x RSSI LEDs (2x red, 2x green)
 - UART (115200 8N1) and GPIO (J9) headers on PCB

Flashing instructions:

 The original firmware is based on OpenWrt so a sysupgrade image can be
 installed via the stock web GUI.

 The U-boot bootloader also contains a backup TFTP client to upload the
 firmware from. Upon boot, it checks its ethernet network for the IP
 192.168.1.10. Host a TFTP server and provide the image to be flashed as
 file firmware_auto.bin.

Run-tested on hardware. Thank you all for the feedback so far.

Changes since v2:

 -Formatting fixes
 -Removed the pin muxer for real this time. Thank you Adrian!
 -Added proper functionality to the WLAN pin.

Closed questions:
 -The memory error mentioned above is not reproducible on another router.
    Assuming hardware defect.

Open questions:
 -The LED list in the LED configuration tab, along with normal LEDs, has
    ath9k-phy0 listed. Why?

 -I could not reproduce RSSI LED behaviour during test.
    None lit up on connecting to the router via Wi-Fi.

 -Could you refer me to a style guide? Some proposed fixes I can't
    understand yet.
