I've just finished the new PCB revision:
With eight solder jumpers (SJ1-8) it is possible now "configure" the board to use an EPM240T100 or EPM570T100 CPLD (the idea to allow the choice between an EPM240 and an EPM570 was suggested by Hacker404).
In the back side there is a short note on how use the solder jumpers.
I've also added a switch and a led for the DEV_OE signal, because using the previous board version I realized that it would have been more handy.
Now some more checks before send the files to the PCB service...
