   1 NAND support for Marvell Orion SoC platforms
   2
   3 Required properties:
   4 - compatible : "marvell,orion-nand".
   5 - reg : Base physical address of the NAND and length of memory mapped
   6         region
   7
   8 Optional properties:
   9 - cle : Address line number connected to CLE. Default is 0
  10 - ale : Address line number connected to ALE. Default is 1
  11 - bank-width : Width in bytes of the device. Default is 1
  12 - chip-delay : Chip dependent delay for transferring data from array to read
  13                registers in usecs
  14
  15 The device tree may optionally contain sub-nodes describing partitions of the
  16 address space. See partition.txt for more detail.
