Subject: [U-Boot] [PATCH v2 0/2] SPI flash update command
Date: Fri, 28 Jun 2013 09:43:51 +0200 [thread overview]
Message-ID: <1372405433-30384-1-git-send-email-gerlando.falauto@keymile.com> (raw)
Hi,
this patchset allows "sf update" to erase+write a number of bytes which is not a
multiple of the sector size. Start address must still be sector-aligned though.
The first patch trivially makes it such it will always erase an entire sector
before writing, regardless of the amount of data to write (i.e. the last sector
is erased completely before writing it only partially).
The second patch just makes sure that the original data at the end of the sector
is written back so to apparently remain unchanged.
Changes from v1 [April, 03, 2012 (!)]:
- Rebased on top of u-boot-spi/master
Gerlando Falauto (2):
cmd_sf: let "sf update" erase last sector as a whole
cmd_sf: "sf update" preserve the final part of the last sector
