[PATCH 00/14] EFI capsule update support for IOT2000 devices

[Jan Kiszka <jan.kiszka-kv7WeFo6aLtBDgjK7y7TUQ@public.gmane.org>]

Last chunk: This backports EFI capsule updates, primarily for the use
with the IOT2020 and IOT2040, the latter with Quark-proprietary security
header format. The feature should also work for the Galileo Gen 2 and,
at least conceptually, for any EFI capsule update compatible firmware.
