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.
