-Required properties:
-- compatible : "marvell,orion-nand".
-- reg : Base physical address of the NAND and length of memory mapped
-	region
-
-Optional properties:
-- cle : Address line number connected to CLE. Default is 0
-- ale : Address line number connected to ALE. Default is 1
-- bank-width : Width in bytes of the device. Default is 1
-- chip-delay : Chip dependent delay for transferring data from array to read

-The device tree may optionally contain sub-nodes describing partitions of the
-address space. See partition.txt for more detail.
