Definitely this make sense to me but the point is if this should be the part of this patch or just separate altera.c/xilinx.c file which is able to detect and check this format. I am not saying that it can't be there but currently without any code I can't see any reason why there should be hook for code which doesn't exist. M -- Michal Simek, Ing.
