Previously WORK_AREA_GUEST_TYPE was cleared in SetCr3ForPageTables64.
This is workable for Legacy guest and SEV guest. But it doesn't work
after Intel TDX is introduced. It is because all TDX CPUs (BSP and APs)
start to run from 0xfff0,

Previously OvmfPkg/ResetVector uses the Main.asm in
UefiCpuPkg/ReseteVector/Vtf0. In this Main.asm there is only Main16
entry point.
This patch-set is to introduce Intel TDX into Ovmf. Main32 entry point
is needed in Main.asm by Intel TDX.

Making baselib implementation depend on MemoryAllocationLib (indirectly on Pei
Service and gBS), it may prevent this base API using at some seneraio. i don't
think it's better.
Add this parameter and make this parameter is optional,
1, when NULL, use the local 256 bytes stack
2, if 256 bytes
Hi Ray,
In this patch, we added a shared file AcpiTable.c for both universal payload
and non-universal payload.
The exposed API from this file is: EFI_STATUS BuildHobFromAcpi ( IN UINT64
AcpiTableBase);
This function will build an ACPI board HOB based on the information from ACPI
table.
Hey Ray,
In my opinion that spec is too complicated. For some cases it is
obvious, but I think the last anyone wants to see is a (STATIC_)ASSERT
before most QuickSort calls to ensure the element size *really* is <=
256 Bytes. In my opinion, there are two roads:
1) Make the parameter
