MTD core:
* Handle possible -EPROBE_DEFER from parse_mtd_partitions()

NAND core:
* Fix error handling in nand_prog_page_op() (x2)
* Add a helper to retrieve the number of ECC bytes per step
* Add a helper to retrieve the number of ECC steps
* Let ECC engines advertize the exact number of steps
* ECC Hamming:
  - Populate the public nsteps field
  - Use the public nsteps field
* ECC BCH:
  - Populate the public nsteps field
  - Use the public nsteps field

Raw NAND core:
* Add support for secure regions in NAND memory
* Try not to use the ECC private structures
* Remove duplicate include in rawnand.h
* BBT:
  - Skip bad blocks when searching for the BBT in NAND

Raw NAND controller drivers:

  - Use dma_mapping_error() for error check
  - Add missing nand_cleanup() in error path
  - Return actual error code instead of -ENODEV
  - Update last code word register
  - Add helper to configure location register
  - Rename parameter name in macro
  - Add helper to check last code word
  - Convert nandc to chip in Read/Write helper
  - Update register macro name for 0x2c offset
* GPMI:
  - Fix a double free in gpmi_nand_init
* Rockchip:
  - Use flexible-array member instead of zero-length array
* Atmel:
  - Update ecc_stats.corrected counter
* MXC:
  - Remove unneeded of_match_ptr()
* R852:
  - replace spin_lock_irqsave by spin_lock in hard IRQ
* Brcmnand:

SPI-NAND core:
* Add missing MODULE_DEVICE_TABLE()

SPI-NAND drivers:
* gigadevice: Support GD5F1GQ5UExxG
mtd: rawnand: qcom: Use dma_mapping_error() for error check

dma_mapping_error() should be used for checking the error value of
dma_map_resource() API.
