In-Reply-To: 

Changes since v2:
-Addressed the comments from Jian Wang
 - CommonMmServicesLib library implemented in MdePkg.
 - Picked the Reviewed-by tags from Ard Biesheuvel.

Changes since v1:
-Addressed the comments from Liming Gao
 - StandaloneMmServicesTableLib library implemented in MdePkg.
- Addressed all the comments from Ard Biesheuvel.
- For comment from Jian Wang about avoiding if..else, this
  requires a bit more clarity and so this comment has not
  been addressed.
- All the patches in this series can be pulled from
  https://github.com/jagadeeshujja/edk2.git branch: topics/aarch64_secure_vars

Changes since RFC v4:
- Addressed all the comments from Liming Gao
  - Added an additional PCD 'PcdStandaloneMmCodeEnabled' to indicate
    presence of StandaloneMM support.
  - MdePkg.dec file updated to include StandaloneMmServiceTableLib and
    StandaloneMmRuntimeDxe library.
  - Platform specific changes will be posted in a seperate patchset.
  - AsmLfence wrapper function is supported for AArch64 platforms.
  - All the patches in this series can be pulled from
    https://github.com/jagadeeshujja/edk2 (branch: topics/aarch64_secure_vars)

Changes since RFC v3:
- Addressed all the comments from Liming Gao
  - Added a AArch64 implementation of AsmLfence which is a wrapper for
    MemoryFence. The changes in variable service driver in v3 of this
    patchset that used MemoryFence instead of AsmLfence have been removed.
  - Added StandaloneMmServicesTableLib.h and StandaloneMmRuntimeDxe
    library into MdePkg.
  - Renamed PcdStandaloneMmEnable as PcdStandaloneMmVariableEnabled and
    added to in to MdePkg.
  - Now with above changes, edk2 packages don't need to depend on
    StandaloneMmPkg/StandaloneMmPkg.dec
- Addressed comments from Ting Ye
  - Removed the hacks in the v3 version.
  - Will relook into the “TimerWrapp.c” file and add a appropriate
    implementation of this for MM Standalone mode code.

Changes since RFC v2:
- Added 'Contributed-under' tag, removed Change-ID tag and
  maintained a single signed-off-by for the all the patches.

Changes since RFC v1:
- Addressed all the comments from Liming Gao
  - Removed the use of #ifdef/#else/#endif and used a Pcd instead to
    select between MM and non-MM paths.
  - Removed all dependencies on edk2-platforms.
  - Dropped the use of mMmst and used gSmst instead.
  - Added a dummy implementation UefiRuntimeServiceTableLib for
    MM_STANDALONE usage
- Replaced all uses of AsmLfence with MemoryFence from variable
  service code.
- Add a new StandaloneMmRuntimeDxe library to for use by non-MM code.

This patch series extends the existing secure variable service support for
use with Standalone MM. This is applicable to paltforms that use Standalone
Management Mode to protect access to non-volatile memory (NOR flash in case
of these patches) used to store the secure EFI variables.

The first patch pulls in additional libraries from the staging branch of
StandaloneMmPkg into the edk2's StandaloneMmPkg. The existing secure variable
service implementation supports only the traditional MM mode and so the rest
of the patches extends the existing secure variable service support to be
useable with Standalone MM mode as well.
