Subject: [PATCH] Add 8devices CARAMBOLA2 support.

This is based on the AR933x (Hornet) SoC from Qualcomm Atheros.

It's a much nicer board to do development on - 64MB RAM, 16MB flash.
The development board breaks out the GPIO pins, ethernet, serial (via
a USB<->RS232 chip), USB host and of course a small wifi antenna.

Everything but the wifi works thus far.
