There's multiple bitfile options which do commit some pins to special functions 
like the actual STEP/DIR.  The special functions can usually be turned off to 
make the pin a GPIO.

Inside the LinuxCNC HAL, you can change which STEP/DIR pair goes to which axis, 
and associate specific GPIO pins with being limit switch inputs and such.
