Re: [PATCH V3 0/6] Add new EfiLocateXXXAcpiTable() APIs

["Gao, Liming" <liming.gao@intel.com>]

Star:
  The change in MdePkg is good. Because you add two APIs in UefiLib library class, could you also update FrameworkUefiLib in IntelFrameworkPkg?

Thanks

> 2. Call EfiLocateFirstAcpiTable() to locate FACS after FACS is installed

> 3. Call EfiLocateFirstAcpiTable() to locate FADT/DSDT/FACS/FPDT/DMAR

> 4. Call EfiLocateNextAcpiTable() to locate SSDTs at late phase, all
>    SSDTs are returned correctly.
> 5. Run same test cases above after setting PcdAcpiExposedTableVersions
