+  Resets the entire platform.
+
+  @param[in] ResetType          The type of reset to perform.
+  @param[in] ResetStatus        The status code for the reset.
+  @param[in] DataSize           The size, in bytes, of ResetData.
+  @param[in] ResetData          For a ResetType of EfiResetCold, EfiResetWarm, or
+                                EfiResetShutdown the data buffer starts with a Null-terminated
+                                string, optionally followed by additional binary data.
+                                The string is a description that the caller may use to further
+                                indicate the reason for the system reset.
+                                For a ResetType of EfiResetPlatformSpecific the data buffer
+                                also starts with a Null-terminated string that is followed
+                                by an EFI_GUID that describes the specific type of reset to perform.
