[GIT PULL] MTD updates for v4.8-rc1

[Brian Norris]

Hi Linus,

The following changes since commit 1a695a905c18548062509178b98bc91e67510864:

  Linux 4.7-rc1 (2016-05-29 09:29:24 -0700)

  mtd: spi-nor: don't build Cadence QuadSPI on non-ARM (2016-07-19 19:48:48 -0700)

Please note that there is a small conflict with the net-wireless tree,
because a small BCMA Kconfig change that was taken there (to fix up some
build issues) conflics with another small description change in this
pull request. The resolution should be trivial, but I can provide a
resolution if you'd like.

MTD updates for v4.8:

NAND:

  Updates from Boris:

    """
    This pull request contains only one notable change:
    * Addition of the MTK NAND controller driver

    And a bunch of specific NAND driver improvements/fixes. Here are the
    changes that are worth mentioning:
    * A few fixes/improvements for the xway NAND controller driver
    * A few fixes for the sunxi NAND controller driver
    * Support for DMA in the sunxi NAND driver
    * Support for the sunxi NAND controller IP embedded in A23/A33 SoCs
    * Addition for bitflips detection in erased pages to the brcmnand driver
    * Support for new brcmnand IPs
    * Update of the OMAP-GPMC binding to support DMA channel description
    """

  In addition, some small fixes around error handling, etc., as well as one
  long-standing corner case issue (2.6.20, I think?) with writing 1 byte less
  than a page.

NOR:

 * Rework some error handling on reads and writes, so we can better handle (for
   instance) SPI controllers which have limitations on their maximum transfer size

 * Add new Cadence Quad SPI flash controller driver

 * Add new Atmel QSPI flash controller driver

 * Add new Hisilicon SPI flash controller driver

 * Support a few new flash, and update supported features on others

 * Fix the logic used for detecting a fully-unlocked flash

And other miscellaneous small fixes.
