| 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>; |
| }; |
| }; |
