+Date: Sun, 17 May 2015 18:48:38 +0200
+Subject: [PATCH 4/8] mtd: part: add generic parsing of linux,part-probe
+
+This moves the linux,part-probe device tree parsing code from
+physmap_of.c to mtdpart.c. Now all drivers can use this feature by just
+providing a reference to their device tree node in struct
+mtd_part_parser_data.

++- linux,part-probe: list of name as strings of the partition parser
++ which should be used to parse the partition table.
++ They will be tried in the specified ordering and
++ the next one will be used if the previous one
++ failed.
++
++ Example: linux,part-probe = "cmdlinepart", "ofpart";
++
++ This is also the default value, which will be used
++ if this attribute is not specified. It could be
++ that the flash driver in use overwrote the default
++ value and uses some other default.
++
++ Possible values are: bcm47xxpart, afs, ar7part,
++ ofoldpart, ofpart, bcm63xxpart, RedBoot, cmdlinepart
++
+ The ECC strength and ECC step size properties define the correction capability
+ of a controller. Together, they say a controller can correct "{strength} bit
+ errors per {size} bytes".
