+ This is a macro defined function, in fact, the function is
+ MiscOnboardDeviceFunction (RecordType, RecordLen, RecordData, LogRecordData)
+ This function makes boot time changes to the contents of the
+ MiscOnboardDevice structure.
+
+ @param MiscOnboardDevice The string which is used to create the function
+ The Arguments in fact:
+ @param RecordType Type of record to be processed from the Data
+ Table. mMiscSubclassDataTable[].RecordType
+ @param RecordLen Size of static RecordData from the Data Table.
+ mMiscSubclassDataTable[].RecordLen
+ @param RecordData Pointer to RecordData, which will be written to
+ the Data Hub
+ @param LogRecordData TRUE to log RecordData to Data Hub. FALSE when
+ there is no more data to log.
+
+ @retval EFI_SUCCESS *RecordData and *LogRecordData have been set.
+ @retval EFI_UNSUPPORTED Unexpected RecordType value.
+ @retval EFI_INVALID_PARAMETER One of the following parameter conditions was
+ true: RecordLen was zero. RecordData was NULL.
+ LogRecordData was NULL.
