Details:

We added a module to able to read EFI variables from configfile. Currently we
use it for Secure Boot. This allows us to do following in grub.cfg:

# check whether Secure Boot is enabled
get_efivar -t uint8 SecureBoot efi_secure_boot


if [ $efi_secure_boot = 1 ]; then
    # secure boot is enabled, boot our secure OS
elif
    # secure boot is disabled: enable it, boot insecure OS etc
fi


We would like to contribute it back because it seems useful for the community.
