Merge tag 'mtd/for-4.20' of git://git.infradead.org/linux-mtd

Pull mtd updates from Boris Brezillon:
 "SPI NOR core changes:
   - Support non-uniform erase size
   - Support controllers with limited TX fifo size

 Driver changes:
   - m25p80: Re-issue a WREN command after each write access
   - cadence: Pass a proper dir value to dma_[un]map_single()
   - fsl-qspi: Check fsl_qspi_get_seqid() return val make sure 4B
     addressing opcodes are properly handled
   - intel-spi: Add a new PCI entry for Ice Lake

 Raw NAND core changes:
   - Two batchs of cleanups of the NAND API, including:
      * Deprecating a lot of interfaces (now replaced by ->exec_op()).
      * Moving code in separate drivers (JEDEC, ONFI), in private files
        (internals), in platform drivers, etc.
      * Functions/structures reordering.
      * Exclusive use of the nand_chip structure instead of the MTD one
        all across the subsystem.
   - Addition of the nand_wait_readrdy/rdy_op() helpers.

 Raw NAND controllers drivers changes:
   - Various coccinelle patches.
   - Marvell:
      * Use regmap_update_bits() for syscon access.
      * More documentation.
      * BCH failure path rework.
      * More layouts to be supported.
      * IRQ handler complete() condition fixed.
   - Fsl_ifc:
      * SRAM initialization fixed for newer controller versions.
   - Denali:
      * Fix licenses mismatch and use a SPDX tag.
      * Set SPARE_AREA_SKIP_BYTES register to 8 if unset.
   - Qualcomm:
      * Do not include dma-direct.h.
   - Docg4:
      * Removed.
   - Ams-delta:
      * Use of a GPIO lookup table
      * Internal machinery changes.

 Raw NAND chip drivers changes:
   - Toshiba:
      * Add support for Toshiba memory BENAND
      * Pass a single nand_chip object to the status helper.
   - ESMT:
      * New driver to retrieve the ECC requirements from the 5th ID
        byte.

  MTD changes:
   - physmap cleanups/fixe
   - gpio-addr-flash cleanups/fixes"
