Correct, it fixes the issue. However, since few changes might have gone
to the Kconfig, the patch does not apply cleanly. Below is the patch, just
a retake of the earlier one, but on the latest code. 

And it got mangled a bit along the way.  Plus, the original one
goofed up Kconfig dependency displays ... both issues fixed in
this version, against current mainline GIT.

If someone can verify all four PPC/OF/OHCI configs build on
on PPC64, I'm OK with it.

Dave,

Sorry for being late. The patch fixes the issue on the latest git for
PPC64. Infact, the whole drivers/usb/host/ builds just fine:

linux-2.6 # make drivers/usb/host/
  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h
  SYMLINK include/asm -> include/asm-powerpc
  CALL    scripts/checksyscalls.sh
  CC      drivers/usb/host/ohci-hcd.o
  CC      drivers/usb/host/pci-quirks.o
  CC      drivers/usb/host/uhci-hcd.o
  LD      drivers/usb/host/built-in.o
  CC [M]  drivers/usb/host/isp116x-hcd.o
  CC [M]  drivers/usb/host/u132-hcd.o

You can check in the patch now.

Dave,

Have you checked in this patch ? Or, does it require some more
modification/updates from somebody´s side ?

Subject: fix build failure for PPC64 randconfig [usb/ohci]

We could just make the USB_OHCI_HCD_PPC_OF option implicit
and selected only if at least one of USB_OHCI_HCD_PPC_OF_BE
and USB_OHCI_HCD_PPC_OF_LE are set.
