MdeModulePkg/ScsiDiskDxe: Support Storage Security Command Protocol 

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1546

This patch implements the EFI_STORAGE_SECURITY_COMMAND_PROTOCOL in the
ScsiDiskDxe driver.

Support is currently limited to the RPMB Well-known LUN for UFS devices.

/**
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.
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 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.
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
SecurityProtocolSpecificData. If the underlying protocol command requires a
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.
If PayloadBuffer is NULL and PayloadBufferSize is non-zero, the function shall
return EFI_INVALID_PARAMETER.
