If you search the archives, you'll find some posts of people working on
PCI USB drivers, but I don't think any patches have been posted yet.

If you can avoid it, please try not to create a new OHCI driver. We're
currently trying to make the existing OHCI drivers generic by adding
board and cpu dependent hooks (see doc/README.generic_usb_ohci). Usually
very little cpu and board dependent code is necessary.
This code is currently still in the testing-USB branch (I'm in the
process of merging it to the new u-boot-usb repository right now) and
will sooner or later will be merged into the main branch. Maybe you can
find a clean way to add PCI USB support the generic driver?
