Module Name:
MiscOnboardDeviceFunction.c
Abstract:
Create the device path for the Onboard device.
The Onboard device information is Misc. subclass type 8 and SMBIOS type 10.

/**
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.
