Tests to see if this driver supports a given controller. If a child device is provided,
it 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 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().
Since 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.
@param[in] ControllerHandle The handle of the controller to test. This handle
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
by RemainingDevicePath are both supported by this
bus driver.
@retval EFI_SUCCESS The device specified by ControllerHandle and
RemainingDevicePath is supported by the driver specified by This.
@retval EFI_ALREADY_STARTED The device specified by ControllerHandle and
RemainingDevicePath is already managed by the driver
specified by This.
@retval EFI_ACCESS_DENIED The device specified by ControllerHandle and
RemainingDevicePath is already managed by a different
driver or an application that requires exclusive access.
Currently not implemented.
@retval EFI_UNSUPPORTED The device specified by ControllerHandle and
RemainingDevicePath is not supported by the driver specified by This.

1. ControllerHandle must be a valid EFI_HANDLE.
2. If RemainingDevicePath is not NULL, then it must be a pointer to a naturally aligned
EFI_DEVICE_PATH_PROTOCOL.
3. Prior to calling Start(), the Supported() function for the driver specified by This must
have been called with the same calling parameters, and Supported() must have returned EFI_SUCCESS.
@param[in] This A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
@param[in] ControllerHandle The handle of the controller to start. This handle
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 a bus driver, if this parameter is NULL, then handles
for all the children of Controller are created by this driver.
If this parameter is not NULL and the first Device Path Node is
not the End of Device Path Node, then only the handle for the
child device specified by the first Device Path Node of
RemainingDevicePath is created by this driver.
If the first Device Path Node of RemainingDevicePath is
the End of Device Path Node, no child handle is created by this
driver.
