At present ofnode only works with a single device tree, for the most part. This is the control FDT used by U-Boot. When booting an OS we may obtain a different device tree and want to modify it. Add some initial support for this into the ofnode API. Note that we don't permit aliases in this other device tree, since the of_access implementation maintains a list of aliases collected at start-up. Also, we don't need aliases to do fixups in the other FDT. So make sure that flat tree and live tree processing are consistent in this area. Signed-off-by: Simon Glass <sjg@chromium.org>
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.
