[edk2-devel] [edk2-platforms] [PATCH v1 0/2] Intel/MinPlatform: Add MpInfo2HobPei

[Nate DeSimone]

Newer versions of CpuMpPei produce the gMpInformation2HobGuid. This HOB is
required by newer implementations of the CPU DXE driver, however older
versions of CpuMpPei do not produce it. This can cause backwards
compatibiliity issues if the FSP binary was built with an older version of
EDK II and the OpenBoard code is built with the latest version of EDK II.

To solve this problem, this patch series introduces a new PEIM called
MpInfo2HobPei. This PEIM will check if CpuMpPei creates gMpInformation2HobGuid
and if it does not then MpInfo2HobPei will create it.
