Sorry about the late response.
I wasn't CC'd on either this patch or the "opposite" one. But, I think I
agree with Michal -- enumerating architectures that are allowed to use
UEFI seems safer at this point than a whole-sale enablement (and also
safer than enumerating the architectures that are *not* allowed to use
UEFI).
So, default to "off", list the arches one by one that are allowed to use
UEFI, and (if necessary) customize the command line / pflash switches
for the given arch.
Thanks
Laszlo
