Subject: [PATCH 1/4] mtd: add of_match_table parsing for partition parsers
|
|
|
|
Allow partition parsers to be matched by attaching compatible strings to
|
|
partitions.
|
|
|
|
This allows specifying the expected format of flash partitions for
|
|
matching partition parsers.
|
|
|
|
Example:
|
|
|
|
flash@foo {
|
|
...
|
|
partitions {
|
|
compatible = "fixed-partitions";
|
|
|
|
cfe@0 {
|
|
reg = <0x0 0x10000>;
|
|
label = "cfe";
|
|
read-only;
|
|
};
|
|
|
|
firmware@10000 {
|
|
reg = <0x10000 0x3e0000>;
|
|
label = "firmware";
|
|
compatible = "brcm,bcm63xx-imagetag";
|
|
};
|
|
|
|
nvram@3f0000 {
|
|
reg = <0x3e0000 0x10000>;
|
|
label = "nvram";
|
|
};
|
|
};
|
|
};
