Representing flash partitions in devicetree
Partitions can be represented by sub-nodes of an mtd device. This can be used
on platforms which have strong conventions about which portions of a flash are
used for what purposes, but which don't use an on-flash partition table such
as RedBoot.
#address-cells & #size-cells must both be present in the mtd device and be
equal to 1.
Required properties:
- reg : The partition's offset and size within the mtd bank.
Optional properties:
- label : The label / name for this partition. If omitted, the label is taken
from the node name (excluding the unit address).
- read-only : This parameter, if present, is a hint to Linux that this
partition should only be mounted read-only. This is usually used for flash
partitions containing early-boot firmware images or data which should not be
clobbered.
Examples:
flash@0 {
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
label = "u-boot";
reg = <0x0000000 0x100000>;
read-only;
};
uimage@100000 {
reg = <0x0100000 0x200000>;
};
};
