Pull MTD updates from Brian Norris:
 "NAND:
   - Add sunxi_nand randomizer support
   - begin refactoring NAND ecclayout structs
   - fix pxa3xx_nand dmaengine usage
   - brcmnand: fix support for v7.1 controller
   - add Qualcomm NAND controller driver

  SPI NOR:
   - add new ls1021a, ls2080a support to Freescale QuadSPI
   - add new flash ID entries
   - support bottom-block protection for Winbond flash
   - support Status Register Write Protect
   - remove broken QPI support for Micron SPI flash

  JFFS2:
   - improve post-mount CRC scan efficiency

  General:
   - refactor bcm63xxpart parser, to later extend for NAND
   - add writebuf size parameter to mtdram

  Other minor code quality improvements"
