    USB: xhci: Support xHCI host controllers and USB 3.0 devices. · 74c68741
    Sarah Sharp authored
    This is the first of many patches to add support for USB 3.0 devices and
    the hardware that implements the eXtensible Host Controller Interface
    (xHCI) 0.95 specification.  This specification is not yet publicly
    available, but companies can receive a copy by becoming an xHCI
    Contributor (see http://www.intel.com/technology/usb/xhcispec.htm).
    
    No xHCI hardware has made it onto the market yet, but these patches have
    been tested under the Fresco Logic host controller prototype.
    
    This patch adds the xHCI register sets, which are grouped into five sets:
     - Generic PCI registers
     - Host controller "capabilities" registers (cap_regs) short
     - Host controller "operational" registers (op_regs)
     - Host controller "runtime" registers (run_regs)
     - Host controller "doorbell" registers
    
    These some of these registers may be virtualized if the Linux driver is
    running under a VM.  Virtualization has not been tested for this patch.
