I see lots of different platforms trying to provide access to their
"secure" firmware data to userspace in different ways.  That feels to me
like they are the same thing that userspace would care about in a
unified way.

Unless we expeect userspace tools to have to be platform-specific for
all of this?  That does not seem wise.

what am I missing here?
