/**

  Tests to see if this driver supports a given controller. If a child device is provided,
 | 
						|
  it further tests to see if this driver supports creating a handle for the specified child device.
 | 
						|
 | 
						|
  This function checks to see if the driver specified by This supports the device specified by
 | 
						|
  ControllerHandle. Drivers will typically use the device path attached to
 | 
						|
  ControllerHandle and/or the services from the bus I/O abstraction attached to
 | 
						|
  ControllerHandle to determine if the driver supports ControllerHandle. This function
 | 
						|
  may be called many times during platform initialization. In order to reduce boot times, the tests
 | 
						|
  performed by this function must be very small, and take as little time as possible to execute. This
 | 
						|
  function must not change the state of any hardware devices, and this function must be aware that the
 | 
						|
  device specified by ControllerHandle may already be managed by the same driver or a
 | 
						|
  different driver. This function must match its calls to AllocatePages() with FreePages(),
 | 
						|
  AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
 | 
						|
  Because ControllerHandle may have been previously started by the same driver, if a protocol is
 | 
						|
  already in the opened state, then it must not be closed with CloseProtocol(). This is required
 | 
						|
  to guarantee the state of ControllerHandle is not modified by this function.

						|
  @param[in]  This                 A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.

 | 
						|
                                   must support a protocol interface that supplies
 | 
						|
                                   an I/O abstraction to the driver.
 | 
						|
  @param[in]  RemainingDevicePath  A pointer to the remaining portion of a device path.  This
 | 
						|
                                   parameter is ignored by device drivers, and is optional for bus
 | 
						|
                                   drivers. For bus drivers, if this parameter is not NULL, then
 | 
						|
                                   the bus driver must determine if the bus controller specified

                                   by ControllerHandle and the child controller specified
