Those are expected. Those tasks don't have any input.

Wut?

Ok, I'll look into that. Thanks. It _should_ have worked.

One thing to note - and I should update the documentation about this is
that there are two top level entities:

 - sha256.v    - Top level with 32-bit memory like interface.
 - wb_sha256.v - Top level with Wishbone interface.

When running the coure through synthesis one will have to select one or
the other, not both.

Regarding WB I'm sort of faltering and consider only using a simpler
interface like the one I'm using in sha256.v.
