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";
};
};
};
