NAND support for Marvell Orion SoC platforms
|
|
|
|
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
|
|
registers in usecs
|
|
|
|
The device tree may optionally contain sub-nodes describing partitions of the
|
|
address space. See partition.txt for more detail.
|
|
|
|
Example:
|
|
|
|
nand@f4000000 {
|
|
#address-cells = <1>;
|
|
#size-cells = <1>;
|
|
cle = <0>;
|
|
ale = <1>;
|
|
bank-width = <1>;
|
|
chip-delay = <25>;
|
|
compatible = "marvell,orion-nand";
|
|
reg = <0xf4000000 0x400>;
|
|
|
|
partition@0 {
|
|
label = "u-boot";
|
|
reg = <0x0000000 0x100000>;
|
|
read-only;
|
|
};
|
|
|
|
partition@100000 {
|
|
label = "uImage";
|
|
reg = <0x0100000 0x200000>;
|
|
};
|
|
|
|
partition@300000 {
|
|
label = "dtb";
|
|
reg = <0x0300000 0x100000>;
|
|
};
|
|
|
|
partition@400000 {
|
|
label = "root";
|
|
reg = <0x0400000 0x7d00000>;
|
|
};
|
|
};
