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

Use (UINTN) cast to cast physical or virtual address values to the pointer size before casting from/to a pointer value. Cc: Ilias Apalodimas <ilias.apalodimas@...> Cc: Leif Lindholm

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

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:

Use intermediate (UINTN) cast when casting int from/to pointer. This is needed as UINT64 values cast from/to 32bit pointer for 32bit architectures. Cc: Ard Biesheuvel <ardb+tianocore@...> Cc:

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

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

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

Is this really a *bugfix*? I called what's being fixed "a gap in a generic protection mechanism", in <https://bugzilla.tianocore.org/show_bug.cgi?id=3324#c9>. I don't know if that makes this patch a

This patch fixes the issue observed during BSF file to YAML file conversion. It also addresses the issue during multibyte array data conversion check, for example the data representation of 0xFFFF

Sorry that I missed last time that the "SecMemEncryptSevLib.inf" instance was not extended with a definition for the new function. This update looks OK; my R-b stands. Thanks Laszlo

(1) Relative to v1, the updates are all good (thanks!), except for one: "@return Rax" is actually a regression -- "@return Eax" was correct, in my opinion. This also affects the top of the leading
