[ARM] 4755/1: [AT91] NAND update
Map the complete memory region (SZ_256M) as is done on the other AT91 processors. The SMC_SMARTMEDIA bit should be set in the EBI controller to enable the hardware NAND logic. (Patch from Sascha Erlacher) Signed-off-by: Andrew Victor <linux@maxim.org.za> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
