Add D-BUS interfaces of SMBIOS MDR V2
SMBIOS MDR is an Intel OEM feature which makes BIOS sending SMBIOS table
to BMC through VGA shared memory. These D-Bus interfaces provide a method
for IPMI Commands sync information with the MDRv2 service.
Base on SMBIOS spec DSP0134_3.0.0 and Managed Data Region
Specification Revision 4
Tested:
With the patches in smbios-mdr, BMC can show correct CPU and DIMM
information in Redfish.
