Pull MTD updates from Richard Weinberger:
 "General changes:
   -  Unconfuse get_unmapped_area and point/unpoint driver methods
   -  New partition parser: sharpslpart
   -  Kill GENERIC_IO
   -  Various fixes

  NAND changes:
   -  Add a flag to mark NANDs that require 3 address cycles to encode a
      page address
   -  Set a default ECC/free layout when NAND_ECC_NONE is requested
   -  Fix a bug in panic_nand_write()
   -  Another batch of cleanups for the denali driver
   -  Fix PM support in the atmel driver
   -  Remove support for platform data in the omap driver
   -  Fix subpage write in the omap driver
   -  Fix irq handling in the mtk driver
   -  Change link order of mtk_ecc and mtk_nand drivers to speed up boot
      time
   -  Change log level of ECC error messages in the mxc driver
   -  Patch the pxa3xx driver to support Armada 8k platforms
   -  Add BAM DMA support to the qcom driver
   -  Convert gpio-nand to the GPIO desc API
   -  Fix ECC handling in the mt29f driver

  SPI-NOR changes:
   -  Introduce system power management support
   -  New mechanism to select the proper .quad_enable() hook by JEDEC
      ID, when needed, instead of only by manufacturer ID
   -  Add support to new memory parts from Gigadevice, Winbond, Macronix
      and Everspin
   -  Maintainance for Cadence, Intel, Mediatek and STM32 drivers"
