Merge tag 'for-linus-3.5-20120601' of git://git.infradead.org/linux-mtd

Pull mtd update from David Woodhouse:
 - More robust parsing especially of xattr data in JFFS2
 - Updates to mxc_nand and gpmi drivers to support new boards and device tree
 - Improve consistency of information about ECC strength in NAND devices
 - Clean up partition handling of plat_nand
 - Support NAND drivers without dedicated access to OOB area
 - BCH hardware ECC support for OMAP
 - Other fixes and cleanups, and a few new device IDs

Fixed trivial conflict in drivers/mtd/nand/gpmi-nand/gpmi-nand.c due to
added include files next to each other.
