Merge tag 'for-linus-20160324' of git://git.infradead.org/linux-mtd
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"
