The RamDiskDxe now will report RAM disks with reserved memory type to NFIT in the ACPI table. This commit will also make sure that an NVDIMM root device exists in the \SB scope before reporting any RAM disk to NFIT. To properly report the NVDIMM root device, one will need to append the following content in the [Rule.Common.DXE_DRIVER] field in platform FDF files: RAW ACPI Optional |.acpi RAW ASL Optional |.aml Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Hao Wu <hao.a.wu@intel.com> Reviewed-by: Feng Tian <feng.tian@intel.com> Reviewed-by: Samer El-Haj-Mahmoud <elhaj@hpe.com>
