Hi, all!


I has bought UHCI on Cardbus card.
  SUGOI CARD X3UFL:  http://www.system-talks.co.jp/product/sgc-x3ufl.htm

However not found the uhci at cardbus driver.  I copied and edited
by ohci_cardbus.c to uhci_cardbus.c, and referred to {ohci,uhci}_pci.c.

I was successful to attach uhci at cardbus on evbppc (OPENBLOCKS266).
# cardbus1: unmap mem space ?
#   UHCI must used I/O space...

  LAN - OPENBLOCS266 - cardbus - uhci - url - pppoe - ISP
         (bridge)


But userland was hungup every moment.  X-<
I can't test on i386 machine.  Please test if be interesting you.  ;-)
