hehe, right I *know* what the patch is doing. I can read the diff and
figure out that you're adding support for Quark to PCH UDC because
Quark's USB IP is the same, what I wasking was if that IP was actually
an instance of the chipidea UDC. After looking at the address space
definitions on both drivers, I see that it's not.

So tomorrow I'll look at this patch again.
