Takashi, I understand your concern. On the other hand, if the callbacks 
are well documented, it actually makes the code easier to follow, as it 
separates general algorithms from detailed HW implementation. I can 
certainly add more comments to the callback functions.

Honestly, I do not know which callbacks to remove (apart of those two 
not redefined in Juli). Otherwise I will have to copy/paste serious 
portions of code to juli.c which I would really want to avoid.

As I see it, the clocking code in ice1724 was written for one specific 
implementation. There was no need to do so in a general way and I 
completely understand that. Nevertheless, juli uses a different clock 
implementation and I believe the time has come to make the code in 
ice1724 more general. Unfortunately, I do not know of any other 
technology but callbacks.

What would you recommend?
