1. PI SMBIOS Checkin. Major change include:
1) Produce PI SMBIOS protocol in MdeModulePkg 2) Update all consumers (in CorePkgs and native platform pkgs) to consume SMBIOS protocol instead of DataHub 3) Pass ECC tool; Verify Nt32, Duet, Unix platform git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@9458 6f19259b-4bc3-4df7-8a09-765794883524
