Patrick Rudolph 0bef9ccd43 UefiPayloadPkg: Add support for Firmware Volume Block Protocol
This adds support for FVB in order to support a platform independent
and non-volatile variable store on UefiPayloadPkg. It is required for
non-volatile variable support, TPM support, Secureboot support and more.

Since commit bc744f5893fc4d53275ed26dd8d968011c6a09c1 coreboot supports
the SMMSTORE v2 feature. It implements a SMI handler that is able to
write, read and erase pages in the boot media (SPI flash).
The communication is done using a fixed communication buffer that is
allocated in CBMEM. The existence of this optional feature is advertised
by a coreboot table.
When the SMMSTORE feature is not available the variable emulation is used
by setting PcdEmuVariableNvModeEnable to TRUE.

Add a library for SMMStore to be used in DXE.

The DXE component provides runtime services and takes care of virtual to
physical mapping the communication buffers between SMM and OS.

Make use of the APRIORI DXE to initialize an empty store on the first boot
and set the PCDs to sane values before the variable driver is loaded.

Tests on Intel(R) Xeon(R) E-2288G CPU @ 3.70G showed that the SMI isn't
triggered with a probability of 1:40 of all cases when called in a tight
loop. The CPU continues running and the SMI is triggeres asynchronously
a few clock cycles later. coreboot only handels synchronous APM request
and does nothing on asynchronous APM triggers.

As there's no livesign from SMM it's impossible to tell if the handler
has run. Just wait a bit and try again to trigger a synchronous SMI.

Tests confirmed that out of 5 million tries the SMI is now always handled.

Tested on Linux and Windows 10 on real hardware.
Currently this cannot be tested on coreboot and qemu as it doesn't support
the SMMSTORE on qemu.

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.
