Merge tag 'mtd/for-4.16' of git://git.infradead.org/linux-mtd

Pull MTD updates from Boris Brezillon:
 "MTD core changes:
   - Rework core functions to avoid duplicating generic checks in
     NAND/OneNAND sub-layers
   - Update the MAINTAINERS entry to reflect the fact that MTD
     maintainers now use a single git tree

  MTD driver changes:
   - CFI: use macros instead of inline functions to limit stack usage
     and make KASAN happy

  NAND core changes:
   - Fix NAND_CMD_NONE handling in nand_command[_lp]() hooks
   - Introduce the ->exec_op() infrastructure
   - Rework NAND buffers handling
   - Fix ECC requirements for K9F4G08U0D
   - Fix nand_do_read_oob() to return the number of bitflips
   - Mark K9F1G08U0E as not supporting subpage writes

  NAND driver changes:
   - MTK: Rework the driver to support new IP versions
   - OMAP OneNAND: Full rework to use new APIs (libgpio, dmaengine) and
     fix DT support
   - Marvell: Add a new driver to replace the pxa3xx one

  SPI NOR core changes:
   - Add support to new ISSI and Cypress/Spansion memory parts.
   - Fix support of Micron memories by checking error bits in the FSR.
   - Fix update of block-protection bits by reading back the SR.
   - Restore the internal state of the SPI flash memory when removing
     the device.

  SPI NOR driver changes:
   - Maintenance for Freescale, Intel and Metiatek drivers.
   - Add support of the direct access mode for the Cadence QSPI
     controller"
