Core:
* Remove obsolete macros only used by the old nand_ecclayout struct
* MAINTAINERS: Add entry for Qualcomm NAND controller driver

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
* xway, vf610, txx9ndfm, tegra, stm32, plat_nand, oxnas, omap, mtk, hisi504,
  gpmi, gpio, denali, bcm6368, atmel:
  - Make use of the helper function devm_platform_ioremap_resource{,byname}()

Onenand driver:
* Samsung: Drop Exynos4 and describe driver in KConfig

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