Cool!

(The core are separate repos because they are separate projects in
itself and you should be able to checkout, track a single core if you
wish). IMHO it is very commmon in git-land to have more repos than for
example SVN. I prefer this and see no big problems.)

I'll look at the code and test it. I will also let Quartus loose on the
code since it seems to find different problems than ISE.

Testbenches are good and imho should be in all cores unless it really is
very hard. The oscillator based entropy source for example really kills
the simulator due to combinational loops.
