Here's a set of patches that can determine the secure boot state of the
UEFI BIOS and pass that along to the main kernel image. This involves
generalising ARM's efi_get_secureboot() function and making it mixed-mode
safe.

The patches can be found here also:

at tag:

efi-secure-boot-20161123

Note that the patches are not terminal on the branch.
