Hi guys,

A while ago I started working on adding FuseSoC support for the
cryptech cores to make the build proccess a bit more manageable. It's
not complete yet for the Novena top-level but it's probably not much
work, and I'll gladly help out if anyone wants to give it a shot. The
work in progress + some instructions are available here
