1Atmel NAND flash
2
3Required properties:
4- compatible : "atmel,at91rm9200-nand".
5- reg : should specify localbus address and size used for the chip,
6	and if availlable the ECC.
7- atmel,nand-addr-offset : offset for the address latch.
8- atmel,nand-cmd-offset : offset for the command latch.
9- #address-cells, #size-cells : Must be present if the device has sub-nodes
10  representing partitions.
11
12- gpios : specifies the gpio pins to control the NAND device. detect is an
13  optional gpio and may be set to 0 if not present.
14
15Optional properties:
16- nand-ecc-mode : String, operation mode of the NAND ecc mode, soft by default.
17  Supported values are: "none", "soft", "hw", "hw_syndrome", "hw_oob_first",
18  "soft_bch".
19- nand-bus-width : 8 or 16 bus width if not present 8
20- nand-on-flash-bbt: boolean to enable on flash bbt option if not present false
