York Sun ee52b188ca powerpc/t4qds: Add T4QDS board
The T4240QDS is a high-performance computing evaluation, development and
test platform supporting the T4240 QorIQ Power Architecture™ processor.

SERDES Connections
  32 lanes grouped into four 8-lane banks
  Two “front side” banks dedicated to Ethernet
  Two “back side” banks dedicated to other protocols
DDR Controllers
  Three independant 64-bit DDR3 controllers
  Supports rates up to 2133 MHz data-rate
  Supports two DDR3/DDR3LP UDIMM/RDIMMs per controller
QIXIS System Logic FPGA

Each DDR controller has two DIMM slots. The first slot of each controller
has up to 4 chip selects to support single-, dual- and quad-rank DIMMs.
The second slot has only 2 chip selects to support single- and dual-rank
DIMMs. At any given time, up to total 4 chip selects can be used.

Detail information can be found in doc/README.t4qds

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
