Pull mtd updates from Miquel Raynal:
 "Core:
   - Remove obsolete macros only used by the old nand_ecclayout struct
   - Don't remove debugfs directory if device is in use
   - MAINTAINERS:
      - Add entry for Qualcomm NAND controller driver
      - Update the devicetree documentation path of hyperbus

  MTD devices:
   - block2mtd:
      - Add support for an optional custom MTD label
      - Minor refactor to avoid hard coded constant
   - mtdswap: Remove redundant assignment of pointer eb

  CFI:
   - Fixup CFI on ixp4xx

  Raw NAND controller drivers:
   - Arasan:
      - Prevent an unsupported configuration
   - Xway, Socrates: plat_nand, Pasemi, Orion, mpc5121, GPIO, Au1550nd,
     AMS-Delta:
      - Keep the driver compatible with on-die ECC engines
   - cs553x, lpc32xx_slc, ndfc, sharpsl, tmio, txx9ndfmc:
      - Revert the commits: "Fix external use of SW Hamming ECC helper"
      - And let callers use the bare Hamming helpers
   - Fsmc: Fix use of SM ORDER
   - Intel:
      - Fix potential buffer overflow in probe

     hisi504, gpmi, gpio, denali, bcm6368, atmel:
      - Make use of the helper function devm_platform_ioremap_resource{,byname}()

  Onenand drivers:
   - Samsung: Drop Exynos4 and describe driver in KConfig

  Raw NAND chip drivers:
   - Hynix: Add support for H27UCG8T2ETR-BC MLC NAND

  SPI NOR core:
   - Add spi-nor device tree binding under SPI NOR maintainers

  SPI NOR manufacturer drivers:
   - Enable locking for n25q128a13

  SPI NOR controller drivers:
   - Use devm_platform_ioremap_resource_byname()"
