Min Xu 8b76f23534 OvmfPkg: Enable TDX in ResetVector
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.

Note: Intel TDX is only available on X64, so the Tdx related changes are
in X64 path. In IA32 path, there may be null stub to make the build
success.

This patch includes below major changes.

1. Ia32/IntelTdx.asm
IntelTdx.asm includes below routines used in ResetVector
 - IsTdx
   Check if the running system is Tdx guest.

 - InitTdxWorkarea
   It initialize the TDX_WORK_AREA. Because it is called by both BSP and
   APs and to avoid the race condition, only BSP can initialize the
   WORK_AREA. AP will wait until the field of TDX_WORK_AREA_PGTBL_READY
   is set.

 - ReloadFlat32
   After reset all CPUs in TDX are initialized to 32-bit protected mode.
   But GDT register is not set. So this routine loads the GDT then jump
   to Flat 32 protected mode again.

 - InitTdx
   This routine wrap above 3 routines together to do Tdx initialization
   in ResetVector phase.

 - IsTdxEnabled
   It is a OneTimeCall to probe if TDX is enabled by checking the
   CC_WORK_AREA.

 - CheckTdxFeaturesBeforeBuildPagetables
   This routine is called to check if it is Non-TDX guest, TDX-Bsp or
   TDX-APs. Because in TDX guest all the initialization is done by BSP
   (including the page tables). APs should not build the tables.

 - TdxPostBuildPageTables
   It is called after Page Tables are built by BSP.
   byte[TDX_WORK_AREA_PGTBL_READY] is set by BSP to indicate APs can
   leave spin and go.

2. Ia32/PageTables64.asm
As described above only the TDX BSP build the page tables. So
PageTables64.asm is updated to make sure only TDX BSP build the
PageTables. TDX APs will skip the page table building and set Cr3
directly.

3. Ia16/ResetVectorVtf0.asm
In Tdx all CPUs "reset" to run on 32-bit protected mode with flat
descriptor (paging disabled). But in Non-Td guest the initial state of
CPUs is 16-bit real mode. To resolve this conflict, BITS 16/32 is used
in the ResetVectorVtf0.asm. It checks the 32-bit protected mode or 16-bit
real mode, then jump to the corresponding entry point.

Code Contributions
------------------

To make a contribution to a TianoCore project, follow these steps.

#. Create a change description in the format specified below to
    use in the source control commit log.
#. Your commit message must include your ``Signed-off-by`` signature
#. Submit your code to the TianoCore project using the process
    that the project documents on its web page. If the process is
    not documented, then submit the code on development email list
    for the project.
#. It is preferred that contributions are submitted using the same
    copyright license as the base project. When that is not possible,
    then contributions using the following licenses can be accepted:

-  BSD (2-clause): http://opensource.org/licenses/BSD-2-Clause
-  BSD (3-clause): http://opensource.org/licenses/BSD-3-Clause
-  MIT: http://opensource.org/licenses/MIT
-  Python-2.0: http://opensource.org/licenses/Python-2.0
-  Zlib: http://opensource.org/licenses/Zlib

For documentation:

-  FreeBSD Documentation License
    https://www.freebsd.org/copyright/freebsd-doc-license.html

Contributions of code put into the public domain can also be accepted.

Contributions using other licenses might be accepted, but further
review will be required.

Developer Certificate of Origin
-------------------------------

Your change description should use the standard format for a
commit message, and must include your ``Signed-off-by`` signature.

In order to keep track of who did what, all patches contributed must
include a statement that to the best of the contributor's knowledge
they have the right to contribute it under the specified license.

The test for this is as specified in the `Developer's Certificate of
Origin (DCO) 1.1 <https://developercertificate.org/>`__. The contributor
certifies compliance by adding a line saying

Signed-off-by: Developer Name developer@example.org

where ``Developer Name`` is the contributor's real name, and the email
address is one the developer is reachable through at the time of
contributing.

::

    Developer's Certificate of Origin 1.1

    By making a contribution to this project, I certify that:

    (a) The contribution was created in whole or in part by me and I
        have the right to submit it under the open source license
        indicated in the file; or

    (b) The contribution is based upon previous work that, to the best
        of my knowledge, is covered under an appropriate open source
        license and I have the right under that license to submit that
        work with modifications, whether created in whole or in part
        by me, under the same open source license (unless I am
        permitted to submit under a different license), as indicated
        in the file; or

    (c) The contribution was provided directly to me by some other
        person who certified (a), (b) or (c) and I have not modified
        it.

    (d) I understand and agree that this project and the contribution
        are public and that a record of the contribution (including all
        personal information I submit with it, including my sign-off) is
        maintained indefinitely and may be redistributed consistent with
        this project or the open source license(s) involved.

Sample Change Description / Commit Message
------------------------------------------

::

    From: Contributor Name <contributor@example.com>
    Subject: [Repository/Branch PATCH] Pkg-Module: Brief-single-line-summary

    Full-commit-message

    Signed-off-by: Contributor Name <contributor@example.com>

Notes for sample patch email
````````````````````````````

-  The first line of commit message is taken from the email's subject
   line following ``[Repository/Branch PATCH]``. The remaining portion
   of the commit message is the email's content.
-  ``git format-patch`` is one way to create this format

Definitions for sample patch email
``````````````````````````````````

-  ``Repository`` is the identifier of the repository the patch applies.
    This identifier should only be provided for repositories other than
    ``edk2``. For example ``edk2-BuildSpecification`` or ``staging``.
-  ``Branch`` is the identifier of the branch the patch applies. This
    identifier should only be provided for branches other than
   ``edk2/master``.
    For example ``edk2/UDK2015``,
   ``edk2-BuildSpecification/release/1.27``, or
    ``staging/edk2-test``.
-  ``Module`` is a short identifier for the affected code or
   documentation. For example ``MdePkg``, ``MdeModulePkg/UsbBusDxe``, ``Introduction``, or
    ``EDK II INF File Format``.
-  ``Brief-single-line-summary`` is a short summary of the change.
-  The entire first line should be less than ~70 characters.
-  ``Full-commit-message`` a verbose multiple line comment describing
    the change. Each line should be less than ~70 characters.
-  ``Signed-off-by`` is the contributor's signature identifying them
    by their real/legal name and their email address.

Submodules
----------

Submodule in EDK II is allowed but submodule chain should be avoided
as possible as we can. Currently EDK II contains the following submodules

-  CryptoPkg/Library/OpensslLib/openssl
-  ArmPkg/Library/ArmSoftFloatLib/berkeley-softfloat-3
-  MdeModulePkg/Universal/RegularExpressionDxe/oniguruma
-  MdeModulePkg/Library/BrotliCustomDecompressLib/brotli
-  BaseTools/Source/C/BrotliCompress/brotli

ArmSoftFloatLib is actually required by OpensslLib. It's inevitable
in openssl-1.1.1 (since stable201905) for floating point parameter
conversion, but should be dropped once there's no such need in future
release of openssl.

To get a full, buildable EDK II repository, use following steps of git
command

.. code-block:: bash

  git clone https://github.com/tianocore/edk2.git
  cd edk2
  git submodule update --init
  cd ..

If there's update for submodules, use following git commands to get
the latest submodules code.

.. code-block:: bash

  cd edk2
  git pull
  git submodule update

Note: When cloning submodule repos, '--recursive' option is not
recommended. EDK II itself will not use any code/feature from
submodules in above submodules. So using '--recursive' adds a
dependency on being able to reach servers we do not actually want
any code from, as well as needlessly downloading code we will not
use.
