Subject: [PATCH 0/3] [PATCH 0/3] mtd: nand: omap: Use Software ECC by default
Date: Tue, 5 Aug 2014 13:11:19 +0300 [thread overview]
Message-ID: <1407233482-11642-1-git-send-email-rogerq@ti.com> (raw)
Hi,
In Linux v3.12 and earlier some boards [1] used Software based ECC as
the NAND ECC scheme. In 3.13 commit c66d039197e4 changed that to
Hardware ECC using ROM code ECC layout. This will cause NAND filesystems
created in 3.12 and earlier to be unreadable in v3.13 and later till
they are erased and re-created.
This series fixes this issue by using Software ECC as the default ECC
scheme for the affected boards.
Tested on omap3beagle.
[1] - Affected boards
-omap3beagle
-omap3touchbook
-overo
-am3517crane
-devkit8000
-ldp
-3430sdp
cheers,
