Defines ARM_SVC_ID_FFA_* and ARM_SVC_ID_SP_* identifiers for 32bit
function IDs as per FF-A specification [1]. Defines also generic ARM
SVC identifier macros to wrap 32bit or 64bit identifiers upon target
built architecture. This will allow to factorize 64bit and 32bit in
packages implementation.

This changes modify ArmPkg to prepare building StandaloneMm
firmware for 32bit Arm architectures, factorizing the AArch64
implementation.
This change adds MmCommunicationDxe driver and ArmMmuPeiLib
and ArmmmuStandaloneMmLib libraries to the list of the
standard components build for ArmPkg on when building for an
ARM architecture.
AArch64/ArmMmuStandaloneMmLib.c is moved to its parent
directory and built for both 32bit and 64bit architectures.
This change modifies MmCommunication to use macro
ARM_SMC_ID_MM_COMMUNICATE that is defined to the 32bit or
64bit SMC identifier defined in FF-A specification upon the
target architecture.

Change GenFv for Arm architecture to generate a specific jump
instruction as image entry instruction when the target entry label
is assembled with Thumb instruction set. This is possible since
SecCoreEntryAddress value fetched from the PE32 as its LSBit set when
the entry instruction executes in Thumb mode.

Use intermediate (UINTN) cast when casting int from/to pointer. This
is needed as UINT64 values cast from/to 32bit pointer for 32bit
architectures.

This change allows to build StandaloneMmPkg components for 32bit Arm
StandaloneMm firmware.
This change mainly moves AArch64/ source files to Arm/ side directory
for several components: StandaloneMmCpu, StandaloneMmCoreEntryPoint
and StandaloneMmMemLib. The source file is built for both 32b and 64b
Arm targets.

Hi Etienne,
Thank you for this patch.
I am getting build errors in VariableMmDependency.inf when building for
ARM. Not sure if you are getting these or it is my development
environment (I am building on a Windows Host PC). Can you let me know
which AArch32 GCC compiler you are using, please?
Apart from this, there are some minor comments that I have marked inline
as [SAMI].
With those addressed.

Regards,
Sami Mujawar

[SAMI] Should this definition be in
ArmPkg\Include\IndustryStandard\ArmStdSmc.h?
I can see Patch 2/5 uses the above define in
ArmPkg/Drivers/MmCommunicationDxe/MmCommunication.c.
