Ulf Samuelsson cb82a53266 Add support for the AT91RM9200EK Board.
The AT91RM9200-EK Evaluation Board supports the AT91RM9200
ARM9-based 32-bit RISC microcontroller and enables real-time code development
and evaluation.

Here is the chip page on Atmel website:

with
	- NOR (cfi driver)
	- DataFlash
	- USB OHCI
	- Net
	- I2C (hard)
