Pull MTD update from Brian Norris:
 "Sorry for delaying this a bit later than usual.  There's one mild
  regression from 3.16 that was noticed during the 3.17 cycle, and I
  meant to send a fix for it along with this pull request.  I'll
  probably try to queue it up for a later pull request once I've had a
  better look at it, hopefully by -rc2 at the latest.

  Summary for this pull:

  NAND
   - Cleanup for Denali driver
   - Atmel: add support for new page sizes
   - Atmel: fix up 'raw' mode support
   - Atmel: miscellaneous cleanups
   - New timing mode helpers for non-ONFI NAND
   - OMAP: allow driver to be (properly) built as a module
   - bcm47xx: RESET support and other cleanups

  SPI NOR
   - Miscellaneous cleanups, to prepare framework for wider use (some
     further work still pending)
   - Compile-time configuration to select 4K vs.  64K support for flash
     that support both (necessary for using UBIFS on some SPI NOR)

  A few scattered code quality fixes, detected by Coverity

  See the changesets for more"
