# In this version, the crypto library was changed from openssl to
# gnutls to avoid the license issue. So the dockerfile for sandbox
# CI should be updated for necessary packages as well.
# See my patch, "Dockerfile: Add libgnutls package for building
# mkeficapsule command", I have not tested the docker image though.

As I proposed and discussed in [1] and [2], I have made a couple of
improvements on the current implementation of capsule update in this
patch set.

* add signing feature to mkeficapsule
* add "--guid" option to mkeficapsule
* add man page of mkeficapsule
* update uefi document regarding capsule update
* revise pytests

Prerequisite patches
====================
For azure pipeline (CI),
* "CI: enforce packages upgrade for Msys2 on Windows" [3]

[3] https://lists.denx.de/pipermail/u-boot/2022-February/474701.html

Test
====
* locally passed the pytest which is included in this patch series
  on sandbox built.
  (CONFIG_EFI_CAPSULE_AUTHENTICATE should explicitly be turned on
  in order to exercise the authentication code.)
* passed Azure pipeline
