-Subject: [PATCH] mtd: parsers: ofpart: support BCM4908 fixed partitions
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-BCM4908 partitioning is based on fixed layout but allows specifying
-multiple firmware partitions. It requires detecting which firmware
-partition was used for booting current kernel.
-
-To support such cases without duplicating a lot of code (without copying
-most of the ofpart.c code) support for post-parsing callback was added.
-
-BCM4908 callback simply reads offset of currently used firmware
-partition from the DT. Bootloader specifies it using the "brcm_blparms"
-property.
