This is really a property of the bitfile. It would be really nice to
have a saner system for describing the bitfiles that doesn't rely on
so much out of band stuff.

Eg when doing partial reconfiguration it would be really sane to have
some checks that the full bitfile is the correct basis for the partial
bitfile.

It also seems link Zynq needs an encrypted/not encrypted flag..

I wonder if we should require a Linux specific header on the bitfile
instead? That would make the bitfile self describing at least.
