Pekon Gupta 9e6155b923 mtd: nand: omap: add CONFIG_SPL_NAND_DEVICE_WIDTH to determine NAND device bus-width 
This patch adds CONFIG_SPL_NAND_DEVICE_WIDTH to specify bus-width of NAND device
  CONFIG_SPL_NAND_DEVICE_WIDTH == 16: NAND device with x16 bus-width
  CONFIG_SPL_NAND_DEVICE_WIDTH == 8:  NAND device with x8 bus-width

Need for a separate CONFIG_xx arise from following situations.
(1) SPL NAND drivers does not have framework to parse ONFI parameter page.

(2) if !defined(CONFIG_SYS_NAND_SELF_INIT)
         |- board_nand_init()
         |- nand_scan()
               |- nand_scan_ident()
               |- nand_scan_tail()
   This means board_nand_init() is called before nand_scan_ident(). So NAND
   controller is initialized before the actual probing of NAND device.
   However some controller (like GPMC) need to be specifically configured for
   bus-width of NAND device.
   In such cases, bus-width of the NAND device should be known in advance
   of actual device probing. Hence, CONFIG_SPL_NAND_DEVICE_WIDTH is useful.

(3) Non-ONFI compliant devices need some mechanism to specify device bus-width
   to driver.

README.zfs 

This patch series adds support for ZFS listing and load to u-boot.

To Enable zfs ls and load commands, modify the board specific config file with
#define CONFIG_CMD_ZFS

Steps to test:

1. After applying the patch, zfs specific commands can be seen
   in the boot loader prompt using
	UBOOT #help

	zfsload- load binary file from a ZFS file system
	zfsls  - list files in a directory (default /)

2. To list the files in zfs pool, device or partition, execute
	zfsls <interface> <dev[:part]> [POOL/@/dir/file]
	For example:
	UBOOT #zfsls mmc 0:5 /rpool/@/usr/bin/

3. To read and load a file from an ZFS formatted partition to RAM, execute
	zfsload <interface> <dev[:part]> [addr] [filename] [bytes]
	For example:
	UBOOT #zfsload mmc 2:2 0x30007fc0 /rpool/@/boot/uImage
