-From: Tim Harvey <tharvey@gateworks.com>
-Subject: mtd: allow partial block unlock
-
-This allows sysupgrade for devices such as the Gateworks Avila/Cambria
-product families based on the ixp4xx using the redboot bootloader with
-combined FIS directory and RedBoot config partitions on larger FLASH
-devices with larger eraseblocks.
-
-This second iteration of this patch addresses previous issues:
-- whitespace breakage fixed
-- unlock in all scenarios
-- simplification and fix logic bug
-
-[john@phrozen.org: this should be moved to the ixp4xx folder]
