Merge tag 'for-linus-20140808' of git://git.infradead.org/linux-mtd

Pull MTD updates from Brian Norris:
 "AMD-compatible CFI driver:
   - Support OTP programming for Micron M29EW family
   - Increase buffer write timeout, according to detected flash
     parameter info

  NAND
   - Add helpers for retrieving ONFI timing modes
   - GPMI: provide option to disable bad block marker swapping (required
     for Ka-On electronics platforms)

  SPI NOR
   - EON EN25QH128 support
   - Support new Flag Status Register (FSR) on a few Micron flash

  Common
   - New sysfs entries for bad block and ECC stats

  And a few miscellaneous refactorings, cleanups, and driver
  improvements"
