Pull request for UEFI sub-system for efi-2020-10-rc1 (3)
Up to now UEFI variables where stored in U-Boot environment variables.
Saving UEFI variables was not possible without saving the U-Boot
environment variables. With this patch series file ubootefi.var in the
EFI system partition is used for saving UEFI variables. Furthermore the
UEFI variables are exposed for reading at runtime.
Code corrections for UEFI secure boot are provided.
A buffer overrun in the RSA library is fixed.
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
