/**\r
The Dynamic Tables Framework provisions two classes of ACPI table\r
generators.\r
 - Standard generators: The ACPI table generators implemented by the\r
                        Dynamic Tables Framework.\r
 - OEM generators:      The ACPI table generators customized by the OEM.\r
\r
The Dynamic Tables Framework implements the following ACPI table generators:\r
  - RAW   : This is the simplest ACPI table generator. It simply installs\r
            the ACPI table provided in the AcpiTableData member of the\r
            CM_STD_OBJ_ACPI_TABLE_INFO. The ACPI table data is provided by\r
            the Configuration Manager and is generated using an implementation\r
            defined mechanism.\r
  - DSDT  : The DSDT generator is a clone of the RAW generator. The difference\r
            is in the way the ACPI Table Data is generated from an AML file.\r
  - SSDT  : The SSDT generator is a clone of the RAW generator. The difference\r
            is in the way the ACPI Table Data is generated from an AML file.\r
  - FADT  : The FADT generator collates the required platform information from\r
            the Configuration Manager and builds the FADT table.\r
  - MADT  : The MADT generator collates the GIC information  from the\r
            Configuration Manager and builds the MADT table.\r
  - GTDT  : The GTDT generator collates the Timer information from the\r
            Configuration Manager and builds the GTDT table.\r
  - DBG2  : The DBG2 generator collates the debug serial port information from\r
            the Configuration Manager and builds the DBG2 table.\r
  - SPCR  : The SPCR generator collates the serial port information from the\r
            Configuration Manager and builds the SPCR table.\r
  - MCFG  : The MCFG generator collates the PCI configuration space information\r
            from the Configuration Manager and builds the MCFG table.\r
  - IORT  : The IORT generator collates the IO Topology information from the\r
            Configuration Manager and builds the IORT table.\r
  - PPTT  : The PPTT generator collates the processor topology information from\r
            the Configuration Manager and builds the PPTT table.\r
  - SRAT  : The SRAT generator collates the system resource affinity information\r
            from the Configuration Manager and builds the SRAT table.\r
  - SSDT Serial-Port:\r
            The SSDT Serial generator collates the Serial port information\r
            from the Configuration Manager and patches the SSDT Serial Port\r
            template to build the SSDT Serial port table.\r
  - SSDT CMN-600:\r
            The SSDT CMN-600 generator collates the CMN-600 information\r
            from the Configuration Manager and patches the SSDT CMN-600\r
            template to build the SSDT CMN-600 table.\r
