[U-Boot] [PATCH 4/5] ARM: Add/Improve support for Atmel AT91RM9200DK/EK

Ulf Samuelsson
2009-01-06T20:20:45Z

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.
