There is a comment at line 527 saying:
-- If the S_FPGA will be provided to a core who drives these lines

This should probably change to become a generic so that people can
decide on the behaviour they want. It will then be more visible, not
hidden in the middle of the code. The sentence itself it quite
cryptic. This core should not assume it is used in a board with a
S_FPGA and a A_FPGA.

TODO:
- Check licensing in sources.
- Check the reset signals.
- See if the main state machine can be stuck somewhere.
