[edk2-devel] [PATCH V2 05/10] OvmfPkg: Update EFI_HOB_PLATFORM_INFO with more platform settings

[Min Xu]

RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

This patch-sets is to bring up Legacy guest and Tdx guest without
PEI phase. So platform initialization has to be done in SEC phase.
It is similar with the work of OvmfPkg/PlatformPei. In
OvmfPkg/PlatformPei some PCDs are set during platform initialization,
such as PcdPciMmio64Base. But in PEI-less boot, PCDs cannot be set.
So these values are saved in EFI_HOB_PLATFORM_INFO. Then in the early
stage of DXE phase this hob will be parsed and PCDs are set accordingly.
