Tom Rini 6f7fe31bf6 Merge patch series "am335x: failsafe bootloader update"
Rasmus Villemoes <ravi@prevas.dk> says:

Make it possible to update the (whole) bootloader on am335x robustly,
i.e. so that a power failure or random OOM killing of the update
process or other interruptions do not result in a bricked board.

The order the trial bits gets set is somewhat odd, but is clearly what
happens, and somebody else trying to reverse engineer the ROM code has
observed the same thing: See the TracingVectors.ods in
https://github.com/sjgallagher2/am335xbootrom .

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
