Marek Szyprowski 750c543ca7 cmd: Add MBR partition layout control utility 
Add a 'mbr' command to let users create or verify MBR partition layout
based on the provided text description. The partition layout is
alternatively read from the 'mbr_parts' environment variable. This can be
used in scripts to help system image flashing tools to ensure proper
partition layout.

The syntax of the text description of the partition list is similar to
the one used by the 'gpt' command. Supported parameters are: name
(currently ignored), start (partition start offset in bytes), size (in
bytes or '-' to expand it to the whole free area), bootable (boolean
flag) and id (MBR partition type). If one wants to create more than 4
partitions, an 'Extended' primary partition (with 0x05 ID) has to be
explicitely provided as a one of the first 4 entries.

Here is an example how to create a 6 partitions (3 on the 'extended
volume'), some of the predefined sizes:

> setenv mbr_parts 'name=boot,start=4M,size=128M,bootable,id=0x0e;
  name=rootfs,size=3072M,id=0x83;
  name=system-data,size=512M,id=0x83;
  name=[ext],size=-,id=0x05;
  name=user,size=-,id=0x83;
  name=modules,size=100M,id=0x83;
  name=ramdisk,size=8M,id=0x83'
> mbr write mmc 0

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
