The problem is in the drivers/usb/host/Kconfig:

config USB_OHCI_HCD_PPC_OF_BE
         bool "Support big endian HC"
         depends on USB_OHCI_HCD_PPC_OF
         default y
         select USB_OHCI_BIG_ENDIAN_DESC
         select USB_OHCI_BIG_ENDIAN_MMIO

config USB_OHCI_HCD_PPC_OF_LE
         bool "Support little endian HC"
         depends on USB_OHCI_HCD_PPC_OF
         default n
         select USB_OHCI_LITTLE_ENDIAN

Since its feasible to say 'n' to both we get the compile error.  How  
do we enforce having at least one set?
