In my opinion the number of LE is important to cover all available
features of the Hermes P1 firmware up to v. 3.3 as Phil, VK6PH, always
pointed out that the free room in the EP3C40 is very limited.

I really wondered if I could replace the broken "40" in the early board with the "25". The boards appear to be the same except for the FPGA.
