This will allow consumers to choose a pxe label at runtime instead of having to prompt the user. One good use-case for this, is choosing whether or not to apply a dtbo depending on the hardware configuration. e.g: for TI's AM335x EVM, it would be convenient to apply a particular dtbo only when the J9 jumper is on PRUSS mode. To achieve this, the pxe menu should have 2 labels, one with the dtbo and the other without, then the "pxe_label_override" env variable should point to the label with the dtbo at runtime only when the jumper is on PRUSS mode. This change can be used for different use-cases and bring more flexibilty to consumers who use sysboot/pxe_utils. if "pxe_label_override" is set but does not exist in the pxe menu, the code should fallback to the default label if given, and no failure is returned but rather a warning message.

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 References : -- ZFS GRUB sources from Solaris GRUB-0.97 -- GRUB Bazaar repository Jorgen Lundman <lundman at lundman.net> 2012.
