Patch from Andrew Victor On the Atmel AT91RM9200-DK and -EK boards, a pin is used to control whether the card socket is used for a DataFlash Card or an MMC/SD card. We now default to MMC/SD in the configuration files. (This version of the patch can be applied before Patch 3392/1) Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
