Merge tag 'for-linus-20140610' of git://git.infradead.org/linux-mtd
Pull MTD updates from Brian Norris:
- refactor m25p80.c driver for use as a general SPI NOR framework for
other drivers which may speak to SPI NOR flash without providing full
SPI support (i.e., not part of drivers/spi/)
- new Freescale QuadSPI driver (utilizing new SPI NOR framework)
- updates for the STMicro "FSM" SPI NOR driver
- fix sync/flush behavior on mtd_blkdevs
- fixup subpage write support on a few NAND drivers
- correct the MTD OOB test for odd-sized OOB areas
- add BCH-16 support for OMAP NAND
- fix warnings and trivial refactoring
- utilize new ECC DT bindings in pxa3xx NAND driver
- new LPDDR NVM driver
- address a few assorted bugs caught by Coverity
- add new imx6sx support for GPMI NAND
- use a bounce buffer for NAND when non-DMA-able buffers are used
