From: Rafał Miłecki <rafal at milecki.pl>

My recent work on adding wide support for linux,part-probe was reviewed and
kind of Nack-ed, but fortunately I was pointed to the old (!) patchset from
Brian doing similar thing in a cleaner way.

This patchset picks the important changes from Brian, cleans them and rebases.

Original patches:
(not picked) [RFC PATCH 1/7] mtd: move partition parsers to drivers/mtd/partitions/
(not picked) [RFC PATCH 2/7] mtd: move partition parsers' Kconfig under a sub-menu
(partially)  [RFC PATCH 3/7] doc: dt: mtd: partition: add on-flash format binding
(picked)     [RFC PATCH 4/7] mtd: add of_match_mtd_parser() and of_mtd_match_mtd_parser() helpers
(partially)  [RFC PATCH 5/7] mtd: partitions: factor out "match by name" handling
(picked)     [RFC PATCH 6/7] RFC: mtd: partitions: enable of_match_table matching
(not picked) [RFC PATCH 7/7] mtd: partitions: add Google's FMAP partition parser

At this point this simply adds a full support for "fixed-partitions" binding.
It should also make adding new bindings (like Google's FMAP) easier in the

I've successfully tested this with bcm47xxsflash driver on Tenda AC9 device. I
used following DT node to get "ofpart" driver parse & register my partitions.

&bcma-sflash {
	partitions {
		compatible = "fixed-partitions";
		#address-cells = <1>;
		#size-cells = <1>;

		partition at 0 {
			label = "cfe";
			reg = <0x0000000 0x40000>;

		firmware at 40000 {
			label = "firmware";
			reg = <0x40000 0x7f0000>;
