   - Avoid VLA usage in nftl layers
   - Remove useless .owner assignment in pismo
   - Fix various issues in the CFI driver
   - Improve TRX partition handling expose a DT compat for this part
     parser

  NAND core changes:
   - Add Miquel as a NAND maintainer
   - Add access mode to the nand_page_io_req struct
   - Fix kernel-doc in rawnand.h
   - Support bit-wise majority to recover from corrupted ONFI parameter
     pages
   - Stop checking FAIL bit after a SET_FEATURES, as documented in the
     ONFI spec

  Raw NAND Driver changes:
   - Fix and cleanup the error path of many NAND controller drivers
   - GPMI:
      + Cleanup/simplification of a few aspects in the driver
      + Take ECC setup specified in the DT into account
   - sunxi: remove support for GPIO-based R/B polling
   - MTK:
      + Use of_device_get_match_data() instead of of_match_device()
      + Add an entry in MAINTAINERS for this driver
      + Fix nand-ecc-step-size and nand-ecc-strength description in the
        DT bindings doc
   - fsl_ifc: fix ->cmdfunc() to read more than one ONFI parameter page

  OneNAND driver changes:
   - samsung: use dev_get_drvdata() instead of platform_get_drvdata()

  SPI NOR core changes:
   - Add support for a bunch of SPI NOR chips
   - Clear EAR reg when switching to 3-byte addressing mode on Winbond
     chips

  SPI NOR controller driver changes:
   - cadence: Add DMA support for direct mode reads
   - hisi: Prefix a few functions with hisi_
   - intel:
      + Mark the driver as "dangerous" in Kconfig
      + Fix atomic sequence handling
      + Pass a 40us delay (instead of 0us) to readl_poll_timeout()
   - fsl:
      + fix a typo in a function name
      + add support for IP variants embedded in the ls2080a and ls1080a
        SoCs
   - stm32: request exclusive control of the reset line"
