*changes v2 -> v3*
[PATCH v3 1/3] (new) porting Brian Norri's patch from linux tree
   This patch allows reading of ONFI params independent of controller configuration
   and NAND device width.
[PATCH v3 2/2] rebase [PATCH v2 2/4] on latest release
[PATCH v3 3/3] (new) cleaned remaining GPMC_NAND_ECC_LP_xx macros from OMAP3 platform
Compile Tested#> ./MAKEALL -s omap3 -s omap4 -s omap5 -s dra7xx -s am33xx


*changes v1 -> v2*
[PATCH v2 1/4]: 
  - dropped NAND_BUSWIDTH_AUTO, instead using CONFIG_SYS_NAND_ONFI_DETECTION
  - added check in nand_flash_detect_onfi() for x8 mode
[PATCH v2 2/4]: (new) Adds CONFIG_SYS_NAND_DEVICE_WIDTH
  - updated for auto-detection of bus-width in non-SPL and ONFI_DETECTION mode
  Refer: http://lists.denx.de/pipermail/u-boot/2013-September/163748.html
[PATCH v2 3/4] <no update>
[PATCH v2 4/4] disabled Pulls on output only I/O pads.
  - updated commit description to add details about NAND cape


*original v1*
This series includes independent patch-sets aiming to enable x16 NAND
support on AM33xx boards (like beaglebone-LT).
[PATCH 1/4]: This patch is ported from linux driver/mtd/nand to allow detection
	device-width of NAND by reading ONFI parameter page.
[PATCH 2/4]: enable NAND_BUSWIDTH_AUTO feature in omap_nand.c
[PATCH 3/4]: cleaning of GPMC configs for NAND and NOR

Brian Norris (1):
  mtd: nand: don't use read_buf for 8-bit ONFI transfers

Pekon Gupta (2):
  mtd: nand: omap: add CONFIG_SYS_NAND_DEVICE_WIDTH to determine NAND
    device bus-width
  omap3: remove remnant macros GPMC_NAND_ECC_LP_x8_LAYOUT and
    GPMC_NAND_ECC_LP_x16_LAYOUT
