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) Signed-off-by: Ulf Samuelsson <ulf@atmel.com> Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
