This sounds useful, since I am using a custom developed board using the
Virtex-II Pro. Unfortunately, the patch wouldn't help me much because I
am doing my interrupt setup for most of my custom devices within
modules. You see my hardware has a Virtex-II Pro and a Virtex-II with a
shared (logically) address space (OPB). I have cascaded interrupt
controllers (ask me if anyone wants the code). So it is quite often that
I have a changed hardware and therefore require different drivers.
Rather than downloading to flash the 700k kernel each time while I am
developing, I just download the 6k - 20k modules. Then I store them in
onboard NOR flash.
That's a long way of saying YES, isn't it?
