York Sun 0aadf4aa51 powerpc/t4240qds: Add VDD override 
Allow VDD voltage overriding with a command. This is an add-on feasture of
VID. To override VDD, use command vdd_override with the value of voltage
in mV, for example

vdd_override <voltage in mV, eg. 1050>

The above example will set the VDD to 1.050 volt. Any wrong value out of
range of 0.8188 to 1.2125 volt or invalid string is ignored.

In addition to the command, if overriding VDD is needed earlier in booting
process, save an variable and reboot:

setenv t4240qds_vdd_mv <voltage in mV>
saveenv

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
