Ilias Apalodimas cbea241e93 efidebug: add multiple device path instances on Boot####
The UEFI spec allows a packed array of UEFI device paths in the
FilePathList[] of an EFI_LOAD_OPTION. The first file path must
describe the loaded image but the rest are OS specific.

Previous patches parse the device path and try to use the second
member of the array as an initrd. So let's modify efidebug slightly
and install the second file described in the command line as the
initrd device path.

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
