Min M Xu deee7a100b OvmfPkg: Enable 2 different CpuMpPei and CpuDxe drivers
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3918

In OvmfPkgX64 we enable 2 different CpuMpPei and CpuDxe drivers. The
difference between the drivers is the MpInitLib or MpInitLibUp. This is
acomplished by adding a MpInitLibDepLib.

In IntelTdxX64 we enable 2 versions of CpuDxe drivers. It is because PEI
is skipped in IntelTdxX64.

Min Xu 76fda1def3 OvmfPkg: Call CcProbe in SecMain.c instead of TsIsEnabled
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3902

TdIsEnabled() uses the CPUID instruction. At this point, exception
handling is not established and a CPUID instruction will generate
a #VC and cause the booting guest to crash.

CcProbe() checks Ovmf work area to return the guest type. So call
of CcProbe() instead of TdIsEnabled() to fix the above issue.

Min Xu 2a7e1e890d OvmfPkg: Add CcProbeLib in *.dsc
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3902

CcProbeLib is imported in BaseIoLibIntrinsicSev.
OvmfPkg/Library/CcProbeLib is the OvmfPkg version which checks
OvmfWorkArea to return the Cc guest type. It is included
in OvmfPkgX64.dsc and IntelTdx/IntelTdxX64.dsc.

Other .dsc include the MdePkg/Library/CcProbeLibNull because Cc guest
is not supported in those projects.

Min Xu 44a53a3bdd OvmfPkg: Introduce IntelTdxX64 for TDVF Config-B
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

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 the basic feature of Config-B in OvmfPkg.
 - Add a standalone IntelTdxX64.dsc to a TDX specific directory for a
   *full* feature TDVF. (Align with existing SEV)
 - IntelTdx.dsc includes Tdx/Legacy OVMF basic boot capability. The
   final binary can run on Tdx/Legacy OVMF.
 - PEI phase is skipped.

By design in Config-B there should be more advanced features, such as:
 - RTMR based measurement and measure boot.
 - Remove unnecessary drivers to reduce attack surface, such as
   network stack.

To make the code review more efficiency, Config-B is split into 2 waves:
 - Basic feature of Config-B
 - Advanced feature of Config-B

This patch contains 2 files (IntelTdxX64.dsc/IntelTdxX64.fdf) which
enable the basic feature of Config-B. In the waves of Advanced feature
of Config-B, we will re-visit these 2 files.

TDX_PEI_LESS_BOOT is defined in IntelTdxX64.dsc to indicate it boots up
without PEI phase.

Min Xu 1f29de4d20 OvmfPkg/IntelTdx: Add Sec to bring up both Legacy and Tdx guest
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

OvmfPkg/IntelTdx/Sec is a simplied version of OvmfPkg/Sec. There
are below differences between these 2 Sec
 - IntelTdx/Sec only supports Legacy guest and Tdx guest in X64.
 - IntelTdx/Sec calls PeilessStartup () to jump from SEC to DXE directly.
 - IntelTdx/Sec uses MemoryAllocationLib / HobLib / PrePiLib in
   EmbeddedPkg.

Min Xu 75942a52ae OvmfPkg: Add PrePiHobListPointerLibTdx
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429

This library sets / gets the Hob list pointer in TDX_WORK_AREA.
This is because it is designed to be used in SEC where the value of
global variable cannot be saved, so the Hob list pointer is saved
in TDX_WORK_AREA.

TDX_WORK_AREA shares the same base address as SEV_WORK_AREA which is
pointed by PcdSevEsWorkAreaBase. This PCD will be renamed to
PcdCcWorkAreaBase as Gerd suggested.
