[PATCH 1/5] ARM: Add/Improve support for Atmel AT91RM9200DK/EK
This patchset updates the at91rm9200dk board support to look similar to the rest of the at91 boards, using more modern access functions for I/O instead of direct pointer accesses.
A derivative of the board is added, ---- at91rm9200dk_df - at91rm9200dk with environment in dataflash
Support for the AT91RM9200EK is added ---- at91rm9200ek - at91rm9200ek with environment in nor flash
Support for a generic AT91RM9200 board with dataflash ---- at91rm9200df - at91rm9200 with environment in dataflash and no norflash drivers.
