Having saved environments usually causes inconsistencies while in development workflow. The saved environments conflict with the default ones that U-boot should be updating during development but that doesn't happen and the saved environments need to be reset during bootups to test the changes causing extra debugs. Remove the saved environments as a default. Environments can always be re-enabled locally if one does like them or needs them for some production environment. Optionally, Uenv.txt can also be used on some of the boot media. Signed-off-by: Manorit Chawdhry <m-chawdhry@ti.com>
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.
