REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3479
The UEFI variable drivers such as VariableRuntimeDxe, VariableSmm,
VariableStandaloneMm, etc. (and their dependent protocol/library
stack), typically acquire UEFI variable store flash information
with PCDs declared in MdeModulePkg.
For example:
[Pcd]
gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableBase
gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableBase64
gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableSize
These PCDs work as-is in the StandaloneMm driver if they are not
dynamic such as Dynamic or DynamicEx because PCD services are not
readily available in the Standalone MM environment. Platforms that
use Standalone MM today, must define these PCDs as FixedAtBuild in
their platform build. However, the PCDs do allow platforms to treat
the PCDs as Dynamic/DynamicEx and being able to support that is
currently a gap for Standalone MM.
This patch series introduces a HOB that can be produced by the
platform to provide the same information. The HOB list is
available to Standalone MM.
The PCD declarations are left as-is in MdeModulePkg for backward
compatibility. This means unless a platform wants to use the HOB,
their code will continue to work with no change (they do not need
to produce the HOB). Only if the HOB is found, is its value used
instead of the PCDs.
Due to the large number of consumers of this information, access
to the base address and size values is abstracted in a new library
class (as requested in the v1 series) called VariableFlashInfoLib.
The API of VariableFlashInfoLib does not bind the underlying data
structure to the information returned to library users to allow
flexibility in the library implementation in the future.
V3 changes:
1. To better clarify usage, renamed the members
"NvStorageBaseAddress" and "NvStorageLength" in
"VARIABLE_FLASH_INFO" to "NvVariableBaseAddress" and
"NvVariableLength".
2. Added description comments to the fields in "VARIABLE_FLASH_INFO".
V2 changes:
1. Abstracted flash info data access with VariableFlashInfoLib.
2. Updated package builds in the repo that build the variable and
FTW drivers to include VariableFlashInfoLib.
3. Removed a redundant variable assignment in VariableSmm.c.
4. Updated comments in FtwMisc.c and FaultTolerantWritePei.c to
indicate driver assumption is UINTN (not UINT32)
5. Added a version field to the VARIABLE_FLASH_INFO structure.

Adds a new GUID that is used to identify a HOB that passes variable
flash information to UEFI variable drivers in HOB consumption phases
such as DXE, Traditional MM, and Standalone MM.
This information was previously passed directly with PCDs such
as EfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableBase
and gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableSize.
However, the Standalone MM variable driver instance does not have
direct access to the PCD database. Therefore, this HOB will first
be considered as the source for variable flash information and
if platforms do not produce the HOB, reading the information from
the PCDs directly will be a backup to provide backward
compatibility.

Adds a new library class VariableFlashInfoLib that abstracts access
to variable flash information. The instance provided first attempts
to retrieve information from the Variable Flash Info HOB. If that
HOB is not present, it falls back to the PCDs defined in
MdeModulePkg.
This fall back behavior provides backward compatibility for platforms
that only provide PCDs but also allows platforms that need to
dynamically provide the information using the Variable Flash Info HOB
to do so at runtime.

Michael:
Can you give the suggestion about how to install this variable flash info
hob when it is required? Because VariablePei is early PEIM, how to make sure
the variable flash info hob is installed before GetVariable is called?
On VARIABLE_FLASH_INFO structure definition, the first field is UINT32,
other fields are all UINT64. How about reserve 4 bytes after the first
field? If so, all fields are at the nature alignment address.
Thanks

Hi Liming,
To help move reviews along, I went ahead and sent a v4 patch series with
the following information:
1. More details about when the HOB is required.
2. More details about when the HOB should be installed in the boot flow.
3. A 4 byte reserved field after the "Version" field.
The details are in MdeModulePkg/Include/Guid/VariableFlashInfo.h
V4: https://edk2.groups.io/g/devel/message/88787
CI PR: https://github.com/tianocore/edk2/pull/2768
Regards,
Michael
