Merge tag 'for-linus-20121219' of git://git.infradead.org/linux-mtd

Pull MTD updates from David Woodhouse:
 - Various cleanups especially in NAND tests
 - Add support for NAND flash on BCMA bus
 - DT support for sh_flctl and denali NAND drivers
 - Kill obsolete/superceded drivers (fortunet, nomadik_nand)
 - Fix JFFS2 locking bug in ENOMEM failure path
 - New SPI flash chips, as usual
 - Support writing in 'reliable mode' for DiskOnChip G4
 - Debugfs support in nandsim
