Subject: [U-Boot] [PATCH v4 0/3] introduce nand write.trimffs
Date: Tue, 14 Jun 2011 16:35:04 -0400 [thread overview]
Message-ID: <cover.1308083237.git.bengardiner@nanometrics.ca> (raw)
In-Reply-To: <20110607113405.3e395910@schlenkerla.am.freescale.net>
This series adds a nand write variant which implements the procedure
reccomended in the UBI FAQ [1] of dropping trailing pages of eraseblocks
containing entirely 0xff's.
[1] http://www.linux-mtd.infradead.org/doc/ubi.html#L_flasher_algo
Changes since v3:
* rebased to nand-flash/next where patches 1/4 and 2/4 [v3] were already
applied
* added patch 1/3 [v4] to treat WITH_YAFFS_OOB as a mode
* renumbered 3/4 and 4/4 [v3] to 1/3 and 3/3 [v4], respectively
* remove uneccessary cast
* wrapped README at 80 columns
* prevent access past input buffer end
Changes since v2:
* dropped WITH_DEFAULTS in favour of '0'
* moved copyright header to nand_util patch
* added write.trimffs variant to README.nand
Changes since v1:
* renamed to 'trimffs' from 'ubi'
* wrapped the new feature in #ifdefs
* don't make it default for jffs -- patch dropped
* attribution of the drop_ffs() function from mtd-utils to Artem
