(Sorry, I'm coming to this incredibly late)

This patch is pretty neat and I wish something like this had existed
when I originally wrote the EFI capsule patches.

James, do you have any plans to resubmit this as a non-RFC? If not, do
you mind if I pick this up and rebase my capsule patches ontop of it?

Sort of, but I was stalled trying to work out how to combine with your
capsule patches.  If you're going to do that work, I can resubmit my
stuff as a patch with all the changes based on the review comments and
then you can do the real work ...
