There is a problem to protect the design. So we use GPL but i want to
speak to a lawyer to know what to do. There is a problem concerning the
binaries/hardware issue of the licence. But the licence speak a lot
about source code and VHDL or C, it's always source code.

I don't know exactly where is the limit that Micheal want to put. but i
know that he prefer design rather than thinking about licence issue.
From my point of view, i think that prorietary SoC should be possibly
made with F-CPU code. Maybe we could use the IP sense of view from
opencores.org. They have defined a "simple" Bus for SoC (Wishbones), so
we could defined a fcpu component (IP?). So every thing inside this bloc
is under GPL (or GPL like) the other part is what you want.
