Understood. Using a couple of 100K of flash for this sort of thing
seems expensive, but maybe with current hardware it has become
economical.

I suspect Stallman would want the VHDL (or whatever) source files
included in the package in addition to the generated bitstreams, but I
consider that unnecessary.
