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 series targets building StandaloneMM package for 32bit ARM
architectures. The main parts of the changes move AArch64/*
files to paths suitable for both 32bit and 64bit Arm machines.
Because these changes move file paths, some other edk2 related
source trees must be updated. Up to my knowledge, only edk2-platforms
and edk2-codereview must be synchronised. [1] shows the changes
needed in edk2-platforms to synchronise with these changes.
I will post a patch series for edk2-platforms, including [1] and
some other changes to allow building StandaloneMmPkg for 32bit Arm
platforms.
This change is a resend of [2], rebased to latest master.

Defines ARM_SVC_ID_FFA_* and ARM_SVC_ID_SP_* identifiers for 32bit
function IDs as per SMCCC specification. Defines also generic ARM
SVC identifier macros to wrap 32bit or 64bit identifiers upon target
built architecture.

Changes in ArmPkg to prepare building StandaloneMm firmware for
32bit Arm architectures.
Adds MmCommunicationDxe driver and ArmMmuPeiLib and
ArmmmuStandaloneMmLib libraries to the list of the standard
components build for ArmPkg on when ARM architectures.
Changes path of source file AArch64/ArmMmuStandaloneMmLib.c
and compile it for both 32bit and 64bit architectures.

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.

[SAMI] if condition should evaluate a Boolean value. See

Hi Etienne,
Thank you for this patch.
A space should not be there between a unary operator add its operand.
See
https://edk2-docs.gitbook.io/edk-ii-c-coding-standards-specification/5_source_files/52_spacing#5-2-2-3-do-not-put-space-between-unary-operators-and-their-object
However, the existing code does not follow this anyways.

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.

I can see Patch 2/5 uses the above define in
