REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3249

Intel's Trust Domain Extensions (Intel TDX) refers to an Intel technology
that extends Virtual Machines Extensions (VMX) and Multi-Key Total Memory
Encryption (MKTME) with a new kind of virutal machines guest called a 
Trust Domain (TD). A TD is desinged to run in a CPU mode that protects the
confidentiality of TD memory contents and the TD's CPU state from other
software, including the hosting Virtual-Machine Monitor (VMM), unless
explicitly shared by the TD itself.

There are 2 configurations for TDVF to upstream. See below link for
the definitions of the 2 configurations.
https://edk2.groups.io/g/devel/message/76367

This patch-set is to enable Config-A in OvmfPkg.
 - Merge the *basic* TDVF feature to existing OvmfX64Pkg.dsc. (Align
   with existing SEV)
 - Threat model: VMM is NOT out of TCB. (We don’t make things worse.)
 - The OvmfX64Pkg.dsc includes SEV/TDX/normal OVMF basic boot capability.
   The final binary can run on SEV/TDX/normal OVMF
 - No changes to existing OvmfPkgX64 image layout.
 - No need to add additional security features if they do not exist today
 - No need to remove features if they exist today.
 - RTMR is not supported
 - PEI phase is NOT skipped in either Td or Non-Td

Patch 01 - 33 are changes in SEC phase. Also some libraries in these
patches are workable in SEC/PEI/DXE.

Patch 16 - 29 extract the common codes from OvmfPkg/PlatformPei to a new
PlatformInitLib. After that OvmfPkg/PlatformPei is refactored with this
lib. These 14 patches are currently reviewed in another separate
patch-set. https://edk2.groups.io/g/devel/message/87327

Patch 34 - 39 are changes in PEI phase.

Patch 40 - 44 are changes in DXE phase.

Patch 45 - 47 are for local Apic timer DXE driver.

Code is at https://github.com/mxu9/edk2/tree/tdvf_wave2.v11

v11 changes:
 - Update MpInitlib based on the review comments. Please see
   https://edk2.groups.io/g/devel/message/88089
 - Update the code base to 3ef2071927fa.

v10 changes:
 - Update MpInitLib based on the review comments. Please see the
   discussion: https://edk2.groups.io/g/devel/message/87902
 - Update the code base to ec0b54849b23.

v9 changes:
 - Move the definition of EFI_RESOURCE_MEMORY_UNACCEPTED from MdePkg
   to OvmfPkg as in internal implementation. Because it has not been
   added in PI spec. After the definition is added in PI spec, it can
   be moved to MdePkg.
 - Add definition of new CPUID leaf 0x21 in
   MdePkg/Include/Register/Intel/Cpuid.h.
 - Use switch-case to hanle VC/VE handling together in
   CpuExceptionHandlerLib.
 - Refactor changes for Tdx guest in MpInitLib.
 - Refine the comments in BaseLib and PlatformInitLib.
 - Other minor updates and changes.

v8 changes:
 - Based on the comments of PlatformInitLib and OvmfPkg/PlatformPei,
   a separte patch-set is created for the changes. It is now under review
   https://edk2.groups.io/g/devel/message/87327
 - Based on the comments, TdCall/TdVmCall/TdIsEnabled is wrapped with
   MDE_CPU_IA32 and MDE_CPU_X64.
 - EFI_RESOURCE_ATTRIBUTE_ENCRYPTED is removed based on the TDVF Spec
   update. Instead EFI_RESOURCE_MEMORY_UNACCEPTED is added to indicate
   the memory which to be accepted in TDVF. The corresponding logic
   of AcceptMemory is updated as well. Please see Patch 31.
 - PcdIa32EferChangeAllowed is deleted. Because for Td guest
   IA32_EFER.NXE is set by default. So we only need check whether it has
   been set before it is to be set again. See Patch 35.
 - Based on comments PcdTdxSharedBitMask is defined in
   [PcdsFixedAtBuild, PcdsPatchableInModule, PcdsDynamic, PcdsDynamicEx]
 - Delete un-necessary header files in TdxLib.h.
 - Other minor updates and changes.

v7 changes:
 - Based on the comments from last review, 8 PlatformInitLib patches
   are squashed into 4 patches (#17-#20). These 4 patches are not
   related to Tdx guest. Tdx related codes of PlatformInitLib is
   in #21.
 - gUefiOvmfPkgTdxPlatformGuid is renamed as gUefiOvmfPkgPlatformInfoGuid.
   Because this GUID is used not only by Tdx guest, but also by
   Legacy guest.
 - PlatformInitLibNull is deleted.
 - In PlatformPei Pml4Entries is cap at 512 entries when
   mPhysMemAddressWidth > 48.

v7 not-addressed comments
 - Comments in MpInitLib have not been addressed yet. It will be
   addressed in the following version.
 - Thanks much for your understanding.

v6 changes:
 - PlatformInitLib and OvmfPkg/PlatformPei refactoring are covered in
   patch from 17 - 24. These patches are not related to Tdx guest. Tdx
   related codes of PlatformInitLib is in patch 25.
 - In the previous patch-sets, TdHob is processed in
   OvmfPkg/Sec/IntelTdx.c. Per Gerd's suggestion they are now moved
   to PlatformInitLib/IntelTdx.c. So that they can be reused in Config-B.
 - The default Accept page size is changed from 4K to 2M.
 - The BspAcceptMemoryResourceRange is refactored according to Gerd's
   comment.
 - In ApRunLoop.nasm command field is set to zero as acknowledgement.
   This is a fix based on the ACPI Spec v6.4,Sec titled "Multiprocessor
   Wakeup Structure".

v6 not-addressed comments
 - Comments in MpInitLib have not been addressed yet. It will be
   addressed in the following version.
 - Thanks much for your understanding.

v5 changes:
 - PlatformInitLib is introduced which wraps the common functions in
   OvmfPkg/PlatformPei. It is because there are a lot of duplicated
   codes for Platform initialization in PEI phase and there are at least
   3 variants of PlatformPei. Another reason is that in TDVF Config-B
   PEI-less boot needs the similar initiliazation as PlatformPei. Based
   on the discussion with the community, PlatformInitLib is introduced.
   As the first stage OvmfPkg/PlatformPei is refactored with this lib.
   In the future the other 2 PlatformPei variants will be refactored
   as well.
 - PcdIgnoreVeHalt is deprecated.
 - Add spec link for Mailbox.
 - Other minor changes, such as comments, uncrustify formats, etc.

v5 not-addressed comments
 - Comments in MpInitLib have not been addressed yet. It will be
   addressed in the following version.
 - Some comments may be missed. I will re-visit the review emails.
 - Thanks much for your understanding.

v4 changes:
 - Split the TdxLib into 2 libraries. The TDX basic functions
   (TdCall / TdVmCall / TdIsEnabled) are moved to BaseLib (#2).
   The other functions are in TdxLib. (#3)
 - Based on above changes (TdCall/TdVmCall/TdIsEnabled in BaseLib)
   the TdxLib.inf is not necessary in some Pkgs, such as
   UefiPayloadPkg. The duplicated source code are deleted (BaseIoLib
   is the sample).
 - Drop the Accepting pages with TDX MP service. Instead only BSP
   accepts pages. There maybe boot performance issue. There are some
   mitigations to it, such as 2M accept page size, lazy accept, etc.
   We will re-visit this issue in a separate patch-set.
 - Relocate Mailbox in TdxDxe driver instead of in PlatformPei. This
   is to keep consistence with Config-B (PEI is skipped in Config-B).
 - SetMmioSharedBit in TdxDxe driver instead of in DxeIplPeim after
   CreateIdentityMappingPageTables. This is to keep consistence with
   Config-B (PEI is skipped in Config-B).
 - Some other minor changes, such as switch-case indention.
 - Rebase the code base (commit: 8c06c53b585a) and update the code with
   uncrustify.

v4 not-addressed comments:
 - Comments in MpInitLib have not been addressed yet. It will be
   addressed in the next version.
 - BaseMemEncryptTdxLib is suggested to be merged with
   BaseMemEncryptSevLib. It will be addressed in the next version.
 - Gerd suggests a generic page table walker which is able to set
   and clear bits for a given memory range in both SEV and TDX guest.
   This suggestion will be addressed in the next version.
 - Some comments may be missed. I will re-visit the review emails.
 - Thanks much for your understanding.

v3 changes:
 - LocalApicTimerDxe is split out to be a separate patch-series.
 - VmTdExitLibNull/VmgExitLib are removed. Instead the VmgExitLib
   is extended to handle #VE exception. (Patch 3-5)
 - Split the Tdx support of base IoLib into 4 commits. (Patch 6-9)
 - Alter of MADT table is updated. In previous version it was
   created from scratch. Now it gets the installed table, copy
   it to a larger buffer and append the ACPI_MADT_MPWK to it.
   (Patch 25)
 - Changes in BaseXApicX2ApicLib is refined based on the
   feedbacks. (Add spec link of MSR access definition, rename
   some funtion name, etc.) (Patch 11)
 - Use PcdConfidentialComputingGuestAttr to probe TDX guest instead
   of CPUID. But in some cases PcdConfidentialComputingGuestAttr
   cannot be used because it has not been set yet.
 - Some other minor changes.
 
v3 not-addressed comments:
 - Some of the comments have not been addressed. This is because I
   need more time to consider how to address these comments.
   At the same time I want to submit a new version based on the above
   changes so that community can review in a more efficient way.
   (v2 is the version one month ago).
 - Comments in MpInitLib have not been addressed yet. It will be
   addressed in v4.
 - BaseMemEncryptTdxLib should be merged with BaseMemEncryptSevLib.
   It will be addressed in v4.
 - Some comments may be missed. I will re-visit the review emails.
 - Thanks much for your understanding.

v2 changes:
 - Remove TdxProbeLib. It is to reduce the depencies of the lib.
 - In v1 a new function (AllocatePagesWithMemoryType) is added in
   PeiMemoryAllocationLib. This function is not necessary. It can
   be replaced by PeiServicesAllocatePages.
 - IoLibFifo.c is added in BaseIoLibIntrinsic. This file includes
   the functions of read/write of I/O  port fifo. These functions
   will call TdIoReadFifo or SevIoReadFifo by checking TDX or SEV
   in run-time.
 - DXE related patches are added. (Patch 22-28)
 - Fix typo in commit/comment message, or some minor changes.
 - Rebase the edk2 code base. (4cc1458dbe00)
