Ying Zhang 3aa29de0b0 TPL : introduce the TPL based on the SPL 
Due to the nand SPL on some board(e.g. P1022DS)has a size limit, it can
not be more than 4K. So, the SPL cannot initialize the DDR with the SPD
code. This patch introduces TPL to enable a loader stub that is loaded
by the code from the SPL. It initializes the DDR with the SPD or other
operations.

The TPL's size is sizeable, the maximum size is decided by the memory's
size that TPL runs. It initializes the DDR through SPD code, and copys
final uboot image to DDR. So there are three stage uboot images:
	* spl_boot, * tpl_boot, * final uboot image

README.zfs zfs: Add ZFS filesystem support 2012-08-09 23:42:20 +02:00

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
