As I discussed in [1], I have made a couple of improvements on the current implemenation of capsule update.
Among others, this patch series 1. add signing feature to mkeficapsule 2. remove dtb operation from mkeficapsule 3. add pytest for capsule authentication (on sandbox)
NOTE: I temporarily include Patch#3 in order to show that it is not worth implementing in C as we can do the same thing with a very small shell script.
My intent is *NOT* to merge Patch#3 in upstream.
Prerequisite patches ==================== See Sughosh's [2] and my [3].
Test ==== * passed the pytest which is included in this patch series on sandbox built locally.
Todo ==== * review and update the document for capsule update doc/board/emulation/qemu_capsule_update.rst (but not in this patch series)
