[ARM] 3456/1: AT91RM9200 support for 2.6 (MMC/SD driver)
Patch from Andrew Victor This patch adds support for the MMC/SD card interface on the Atmel AT91RM9200 processor. Original driver was by Nick Randell, but a number of people have subsequently worked on it. It's currently maintained by Malcolm Noyes.
