This series looks much improved to me. I think it can go in as it stands.

One thing I would like to see improved it the definition of the efi class
interface. I don't know how we do something like an abstract base class in
bb-speak, but someone wanting to add another EFI class needs to be able to
learn what the required methods and arguments are. Also, efi_populate()
isn't one of those interfaces, and that should probably not use the
generic efi_ prefix as it is effectively a gummiboot or grub-efi private
method, and should be named accordingly.

But, those are nitpics that can be cleaned up over time as we polish and
extend this mechanism. Time to get this in and get some broader
use/testing.

Ultimately, I'd like to see gummiboot as the default, but I can also just
set that in meta-intel if others do not agree.

Thank you for you efforts here Stefan!
