Stefan Roese eea628199d mtd: Add device-tree support to fsmc_nand
This patch adds support to configure the FSMC NAND driver (used amongst
others on SPEAr platforms) via device-tree instead of platform_data.

* FSMC NAND
Required properties:
- compatible : "st,spear600-fsmc-nand"
- reg : Address range of the mtd chip
- reg-names: Should contain the reg names "fsmc_regs" and "nand_data"
- st,ale-off : Chip specific offset to ALE
- st,cle-off : Chip specific offset to CLE
Optional properties:
- bank-width : Width (in bytes) of the device. If not present, the width
defaults to 1 byte
- nand-skip-bbtscan: Indicates the the BBT scanning should be skipped
Example:
fsmc: flash@d1800000 {
compatible = "st,spear600-fsmc-nand";
#address-cells = <1>;
#size-cells = <1>;
reg = <0xd1800000 0x1000 /* FSMC Register */
0xd2000000 0x4000>; /* NAND Base */
reg-names = "fsmc_regs", "nand_data";
st,ale-off = <0x20000>;
st,cle-off = <0x10000>;
bank-width = <1>;
nand-skip-bbtscan;
partition@0 {
...
};
};
