[edk2-platforms][PATCH 0/4] Arm 32bit support in StandaloneMmRpmb

[Etienne Carriere]

This series brings support for building PlatformStandaloneMmRpmb for
32bit Arm architectures. This series is based on series [1] in edk2
that allows to build StandaloneMm package for 32bit Arm. This series
starts by syncing with paths changes from [1] series, then comes
changes for Arm 32bit support in OpTee drivers and last updates
PlatformStandaloneMmRpmb.dsc for 32bit the ARM architure.

[1] https://edk2.groups.io/g/devel/message/74734

Etienne Carriere (4):
  sync with edk2 where StandaloneMmCpu moved to AArch64/ parent
    directory
  Drivers/OpTee: Add Aarch32 SVC IDs for 32bit Arm targets
  Drivers/OpTee: address cast build warning issue in 32b mode
  Platform/StandaloneMm: build StandaloneMmRpmb for 32bit architectures

Re: [edk2-platforms][PATCH 1/4] sync with edk2 where StandaloneMmCpu moved to AArch64/ parent directory

[Sami Mujawar]

Hi Etienne,

Thank you for this patch.

I would have prefered this patch split in 3 parts (for SgiPkg, Socionext 
and Platform/StandaloneMm). In either case the changes look good to me.

[edk2-platforms][PATCH 2/4] Drivers/OpTee: Add Aarch32 SVC IDs for 32bit Arm targets

[Etienne Carriere]

Add SMCCC function IDs for RPMB read/write service on 32bit architectures.
Define generic SP_SVC_RPMB_READ/SP_SVC_RPMB_WRITE IDs for native target
architecture (32b or 64b).

Changes OpTeeRpmbFvb.c to use architecture agnostic macro
ARM_SVC_ID_FFA_MSG_SEND_DIRECT_REQ for 32b and 64b support.

[edk2-platforms][PATCH 4/4] Platform/StandaloneMm: build StandaloneMmRpmb for 32bit architectures

[Etienne Carriere]

Build PlatformStandaloneMmRpmb for ARM architecture (32bit arm machine).
The generated image targets an execution environment similar to AArch64
StMM secure partition in OP-TEE but in 32bit mode.

GCC flag -fno-stack-protector
added. The stack protection code bring
GOT dependencies we prefer avoid when StMM runs in OP-TEE.

[SAMI] I think BaseStackCheckLib.inf can be moved to the 
[LibraryClasses] section, right?

[SAMI] ArmSvcLib.inf is already present in the [LibraryClasses] section.
[/SAMI]

[SAMI] I think 'MdePkg/MdeLibs.dsc.inc' can be included instead, right 
after the [Defines] section.
This will also fix the build failure for AARCH64.
