+ The GetDevice() function determines the port and port multiplier port number associated with
+ the ATA device described by DevicePath. If DevicePath is a device path node type that the
+ ATA Pass Thru driver supports, then the ATA Pass Thru driver will attempt to translate the contents
+ DevicePath into a port number and port multiplier port number.
+
+ If this translation is successful, then that port number and port multiplier port number are returned
+ in Port and PortMultiplierPort, and EFI_SUCCESS is returned.
+
+ If DevicePath, Port, or PortMultiplierPort are NULL, then EFI_INVALID_PARAMETER is returned.
+
+ If DevicePath is not a device path node type that the ATA Pass Thru driver supports, then
+ EFI_UNSUPPORTED is returned.
+
+ If DevicePath is a device path node type that the ATA Pass Thru driver supports, but there is not
+ a valid translation from DevicePath to a port number and port multiplier port number, then
+ EFI_NOT_FOUND is returned.
