Pull MTD updates from Richard Weinberger:
 "MTD core changes:
   - New AFS partition parser
   - Update MAINTAINERS entry
   - Use of fall-throughs markers

  NAND core changes:
   - Support having the bad block markers in either the first, second or
     last page of a block. The combination of all three location is now
     possible.
   - Constification of NAND_OP_PARSER(_PATTERN) elements.
   - Generic NAND DT bindings changed to yaml format (can be used to
     check the proposed bindings. First platform to be fully supported:
     sunxi.
   - Stopped using several legacy hooks.
   - Preparation to use the generic NAND layer with the addition of
     several helpers and the removal of the struct nand_chip from
     generic functions.
   - Kconfig cleanup to prepare the introduction of external ECC engines
     support.
   - Fallthrough comments.
   - Introduction of the SPI-mem dirmap API for SPI-NAND devices.

  Raw NAND controller drivers changes:
   - nandsim:
      - Switch to ->exec-op().
   - meson:
      - Misc cleanups and fixes.
      - New OOB layout.
   - Sunxi:
      - A23/A33 NAND DMA support.
   - Ingenic:
      - Full reorganization and cleanup.
      - Clear separation between NAND controller and ECC engine.
      - Support JZ4740 an JZ4725B.
   - Denali:
      - Clear controller/chip separation.
      - ->exec_op() migration.
      - Various cleanups.
   - fsl_elbc:
      - Enable software ECC support.
   - Atmel:
      - Sam9x60 support.
   - GPMI:
      - Introduce the GPMI_IS_MXS() macro.
   - Various trivial/spelling/coding style fixes.

  SPI NOR core changes:
   - Print all JEDEC ID bytes on error
   - Fix comment of spi_nor_find_best_erase_type()
   - Add region locking flags for s25fl512s

  SPI NOR controller drivers changes:
   - intel-spi:
      - Avoid crossing 4K address boundary on read/write
      - Add support for Intel Comet Lake SPI serial flash"
