[ARM] 4755/1: [AT91] NAND update
Browse files Browse the repository at this point in the history 
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)
