Extend support for signing in auto-generated (-f auto) FIT. Previously,
it was possible to get signed 'images' subnodes in the FIT using
options -g and -o together with -f auto. This patch allows signing
'configurations' subnodes instead of 'images' ones (which are hashed),
using option -f auto-conf instead of -f auto. Adding also -K <dtb> and
-r options, will add public key to <dtb> file with required = "conf"
property.
Summary:
-f auto => FIT with crc32 images
-f auto -g ... -o ... => FIT with signed images
-f auto-conf -g ... -o ... => FIT with sha1 images and signed confs
Example: FIT with kernel, two device tree files, and signed
configurations; public key (needed to verify signatures) is
added to u-boot.dtb with required = "conf" property.
mkimage -f auto-conf -A arm -O linux -T kernel -C none -a 43e00000 \
-e 0 -d vmlinuz -b /path/to/first.dtb -b /path/to/second.dtb \
-k /folder/with/key-files -g keyname -o sha256,rsa4096 \
-K u-boot.dtb -r kernel.itb
Example: Add public key with required = "conf" property to u-boot.dtb
without needing to sign anything. This will also create a useless FIT
named unused.itb.
mkimage -f auto-conf -d /dev/null -k /folder/with/key-files \
-g keyname -o sha256,rsa4096 -K u-boot.dtb -r unused.itb

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.
