* BCM2835 SMI NAND flash
This driver is a shim between the BCM2835 SMI driver (SMI is a peripheral for
talking to parallel register interfaces) and Linux's MTD layer.
Required properties:
- compatible: "brcm,bcm2835-smi-nand"
- status: "okay"
Optional properties:
- partition@n, where n is an integer from a consecutive sequence starting at 0
- Difficult to store partition table on NAND device - normally put it
in the source code, kernel bootparams, or device tree (the best way!)
- Sub-properties:
- label: the partition name, as shown by mtdinfo /dev/mtd*
- reg: the size and offset of this partition.
- (optional) read-only: an empty property flagging as read only
Example:
nand: flash@0 {
compatible = "brcm,bcm2835-smi-nand";
status = "okay";
partition@0 {
label = "stage2";
// 128k
reg = <0 0x20000>;
read-only;
};
partition@1 {
label = "firmware";
// 16M
reg = <0x20000 0x1000000>;
read-only;
};
partition@2 {
label = "root";
// 2G
reg = <0x1020000 0x80000000>;
};
};
