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:
http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3507
with
- NOR (cfi driver)
- DataFlash
- USB OHCI
- Net
- I2C (hard)
