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]
