    USB: OHCI: make ohci-pci a separate driver · c1117afb
    Manjunath Goudar authored
    This patch splits the PCI portion of ohci-hcd out into its
    own separate driver module, called ohci-pci.
    
    The major point of difficulty lies in ohci-pci's many vendor- and
    device-specific workarounds.  Some of them have to be applied before
    calling ohci_start() some after, which necessitates a fair amount of
    code motion.  The other platform drivers require much smaller changes.
    
    The complete sb800_prefetch() function moved to ohci-q.c,because its
    only related to ohci-pci driver.
    
    USB_OHCI_HCD_PCI symbol no longer dependence on STB03xxx, PPC_MPC52xx and
    USB_OHCI_HCD_PPC_OF that's what removed.
    
    V2:
      - few specific content of pci related code in ohci_pci_start function has been moved to ohci_pci_reset
        and rest of the generic code is written in ohci_start of ohci-hcd.c file.
    V3:
     - ohci_restart() has been called in ohci_pci_reset() function for to reset the ohci pci.
    
    V4:
     -sb800_prefetch() moved to ohci-q.c,because its only related to ohci-pci.
     -no longer _creating_ CONFIG_USB_OHCI_PCI,creating CONFIG_USB_OHCI_HCD_PCI.
     -overrides renamed with pci_override,its giving proper meaning.
    
    V5:
     -sb800_prefetch() moved to pci-quirks.c,because its only related to pci.
    
    V6:
     -sb800_prefetch() function has been moved to pci-quirks.c made as separate patch in 2/3.
     -Most of the generic ohci pci changes moved in 2/3 patch,now this is complete  ohci-pci separation patch.
    
    V7:
     -Unrelated include file has been removed from ohci.h file.
    
    V8:
     -USB_OHCI_HCD_PCI symbol does not dependence on STB03xxx, PPC_MPC52xx and USB_OHCI_HCD_PPC_OF.
