To: edk2-devel; +Cc: Christopher J Zurcher, Jiewen Yao, Jian J Wang, Liming Gao
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1546
V3 changes:
Initialize AlignedBuffer variable in ScsiDiskReceiveData and
ScsiDiskSendData functions. Remove redundant input validation and debug
message in ScsiDiskSendData.
V2 changes:
Split the patch into separate commits for separate packages.
To support RPMB access on UFS devices, support must be added to
the ScsiDiskDxe driver for the Storage Security Command Protocol.

+ 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

+ If the security protocol fails to complete within the Timeout period, the function

+ 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.
+
+ @retval EFI_SUCCESS The security protocol command completed successfully.
+ @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 is NULL and PayloadBufferSize is non-zero.
+ @retval EFI_TIMEOUT A timeout occurred while waiting for the security
+ protocol command to execute.
