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().
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 being managed by the driver
specified by This.
@retval EFI_ACCESS_DENIED The device specified by ControllerHandle and
RemainingDevicePath is already being managed by a different
driver or an application that requires exclusive access.

Send a security protocol command to a device that receives data and/or the result
of one or more commands sent by SendData.
The ReceiveData function sends a security protocol command to the given MediaId.
The security protocol command sent is defined by SecurityProtocolId and contains
the security protocol specific data SecurityProtocolSpecificData. The function
returns the data from the security protocol command in PayloadBuffer.
For devices supporting the SCSI command set, the security protocol command is sent
using the SECURITY PROTOCOL IN command defined in SPC-4.
For devices supporting the ATA command set, the security protocol command is sent
using one of the TRUSTED RECEIVE commands defined in ATA8-ACS if PayloadBufferSize
is non-zero.
If the PayloadBufferSize is zero, the security protocol command is sent using the
Trusted Non-Data command defined in ATA8-ACS.
If PayloadBufferSize is too small to store the available data from the security
protocol command, the function shall copy PayloadBufferSize bytes into the
PayloadBuffer and return EFI_WARN_BUFFER_TOO_SMALL.
If PayloadBuffer or PayloadTransferSize is NULL and PayloadBufferSize is non-zero,
the function shall return EFI_INVALID_PARAMETER.
If the given MediaId does not support security protocol commands, the function shall
return EFI_UNSUPPORTED. If there is no media in the device, the function returns
EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the device,
the function returns EFI_MEDIA_CHANGED.
If the security protocol fails to complete within the Timeout period, the function
shall return EFI_TIMEOUT.
If the security protocol command completes without an error, the function shall
return EFI_SUCCESS. If the security protocol command completes with an error, the
function shall return EFI_DEVICE_ERROR.
@param This Indicates a pointer to the calling context.
@param MediaId ID of the medium to receive data from.
@param Timeout The timeout, in 100ns units, to use for the execution
of the security protocol command. A Timeout value of 0
means that this function will wait indefinitely for the
security protocol command to execute. If Timeout is greater
than zero, then this function will return EFI_TIMEOUT
if the time required to execute the receive data command
is greater than Timeout.
@param SecurityProtocolId The value of the "Security Protocol" parameter of
the security protocol command to be sent.
@param SecurityProtocolSpecificData The value of the "Security Protocol Specific" parameter
of the security protocol command to be sent.
@param PayloadBufferSize Size in bytes of the payload data buffer.
@param PayloadBuffer A pointer to a destination buffer to store the security
protocol command specific payload data for the security
protocol command. The caller is responsible for having
either implicit or explicit ownership of the buffer.
@param PayloadTransferSize A pointer to a buffer to store the size in bytes of the
data written to the payload data buffer.
@retval EFI_SUCCESS The security protocol command completed successfully.
@retval EFI_WARN_BUFFER_TOO_SMALL The PayloadBufferSize was too small to store the available
data from the device. The PayloadBuffer contains the truncated data.
@retval EFI_UNSUPPORTED The given MediaId does not support security protocol commands.
@retval EFI_DEVICE_ERROR The security protocol command completed with an error.
@retval EFI_NO_MEDIA There is no media in the device.
@retval EFI_MEDIA_CHANGED The MediaId is not for the current media.
@retval EFI_INVALID_PARAMETER The PayloadBuffer or PayloadTransferSize is NULL and
PayloadBufferSize is non-zero.
@retval EFI_TIMEOUT A timeout occurred while waiting for the security
protocol command to execute.

Send a security protocol command to a device.
The SendData function sends a security protocol command containing the payload
PayloadBuffer to the given MediaId. The security protocol command sent is
defined by SecurityProtocolId and contains the security protocol specific data

specific padding for the command payload, the SendData function shall add padding
bytes to the command payload to satisfy the padding requirements.
For devices supporting the SCSI command set, the security protocol command is sent
using the SECURITY PROTOCOL OUT command defined in SPC-4.
For devices supporting the ATA command set, the security protocol command is sent
using one of the TRUSTED SEND commands defined in ATA8-ACS if PayloadBufferSize
