1NAND support for Marvell Orion SoC platforms2 3Required properties:4- compatible : "marvell,orion-nand".5- reg : Base physical address of the NAND and length of memory mapped6 region7 8Optional properties:9- cle : Address line number connected to CLE. Default is 010- ale : Address line number connected to ALE. Default is 111- bank-width : Width in bytes of the device. Default is 112- chip-delay : Chip dependent delay for transferring data from array to read13 registers in usecs14 15The device tree may optionally contain sub-nodes describing partitions of the16address space. See mtd.yaml for more detail.17 18Example:19 20nand@f4000000 {21 #address-cells = <1>;22 #size-cells = <1>;23 cle = <0>;24 ale = <1>;25 bank-width = <1>;26 chip-delay = <25>;27 compatible = "marvell,orion-nand";28 reg = <0xf4000000 0x400>;29 30 partition@0 {31 label = "u-boot";32 reg = <0x0000000 0x100000>;33 read-only;34 };35 36 partition@100000 {37 label = "uImage";38 reg = <0x0100000 0x200000>;39 };40 41 partition@300000 {42 label = "dtb";43 reg = <0x0300000 0x100000>;44 };45 46 partition@400000 {47 label = "root";48 reg = <0x0400000 0x7d00000>;49 };50};51
