89   Tests to see if this driver supports a given controller. If a child device is provided,
90   it further tests to see if this driver supports creating a handle for the specified child device.
91 
92   This function checks to see if the driver specified by This supports the device specified by
93   ControllerHandle. Drivers will typically use the device path attached to
94   ControllerHandle and/or the services from the bus I/O abstraction attached to
95   ControllerHandle to determine if the driver supports ControllerHandle. This function
96   may be called many times during platform initialization. In order to reduce boot times, the tests
97   performed by this function must be very small, and take as little time as possible to execute. This
98   function must not change the state of any hardware devices, and this function must be aware that the
99   device specified by ControllerHandle may already be managed by the same driver or a
100   different driver. This function must match its calls to AllocatePages() with FreePages(),
101   AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
102   Because ControllerHandle may have been previously started by the same driver, if a protocol is
103   already in the opened state, then it must not be closed with CloseProtocol(). This is required
104   to guarantee the state of ControllerHandle is not modified by this function.

106   @param[in]  This                 A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
107   @param[in]  ControllerHandle     The handle of the controller to test. This handle
108                                    must support a protocol interface that supplies
109                                    an I/O abstraction to the driver.
110   @param[in]  RemainingDevicePath  A pointer to the remaining portion of a device path.  This
111                                    parameter is ignored by device drivers, and is optional for bus
112                                    drivers. For bus drivers, if this parameter is not NULL, then
113                                    the bus driver must determine if the bus controller specified
114                                    by ControllerHandle and the child controller specified
115                                    by RemainingDevicePath are both supported by this

122                                    specified by This.
