* 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;
