Right. You should have enough memory in your system to tolerate this :-)

Well... even if you use the EDK-integrated linux, it will be
retailored/recompiled, when you change the set of peripherals. When we
defined the virtex BSP, we added the configuration option to reference
an external xpar*.h header file to import HW-specific stuff.

By the way: I am glad Ralf did not yet detect, what we did there. If he
did, he might have taken a FAST car ride from Ulm to Puchheim just to
slap me as often as possible against my head. And her might be right to
do this :-)
