Hello Jiewen and Jian, Does the patch-set look ok for SecurityPkg ?

From: Pierre Gondois <pierre.gond...@arm.com> Bugzilla: Bug 3668 (https://bugzilla.tianocore.org/show_bug.cgi?id=3668) The Arm True Random Number Generator Firmware, Interface 1.0, specification defines an interface between an Operating System (OS) executing at EL1 and Firmware (FW) exposing a conditioned entropy source that is provided by a TRNG back end. This patch-set: - defines a TRNG library class that provides an interface to access the entropy source on a platform. - implements a TRNG library instance that uses the Arm FW-TRNG interface. - Adds RawAlgorithm support to RngDxe for Arm architecture using the Arm FW-TRNG interface. - Enables RNG support using FW-TRNG interface for Kvmtool Guest/Virtual firmware. This patch-set is based on the v2 from Sami Mujawar: [PATCH v2 0/8] Add Raw algorithm support using Arm FW-TRNG interface v2: https://edk2.groups.io/g/devel/message/83775 v3: https://edk2.groups.io/g/devel/message/90845 https://github.com/PierreARM/edk2/tree/Arm_Trng_v3 v4: https://github.com/PierreARM/edk2/tree/Arm_Trng_v4 v5: https://github.com/PierreARM/edk2/tree/Arm_Trng_v5 v6: https://github.com/PierreARM/edk2/tree/Arm_Trng_v6 v7: https://github.com/PierreARM/edk2/tree/Arm_Trng_v7 v8: https://github.com/PierreARM/edk2/tree/Arm_Trng_v8 v8: - Added Reviewed-by/Acked-by from Leif on ArmPkg/SecurityPkg patches. [Leif] - Renamed FID_TRNG_* macros to ARM_SMC_ID_TRNG_*. [Leif] v7: - Removed Reviewed-by from Leif. - Remove Sami's Signed-off. V6: - Added my signed-off on patches authored by Sami. [Leif] - New patch to make it easier to add new libraries in alphabetical order: ArmPkg: Sort HVC/SMC section alphbetically in ArmPkg.dsc [Leif] - Renmaed ArmHvcNullLib to ArmHvcLibNull. [Leif] - Added RISCV64 to the list of VALID_ARCHITECTURES for BaseTrngLibNull. [Leif] - Removed unnecessary space in function parameter documentation ('[in, out]'). [Rebecca] - Updated INF_VERSION to latest spec (1.29) for new libraries. [Rebecca] - Dropped the following patches [Leif]: - ArmPkg/ArmLib: Add ArmHasRngExt() - ArmPkg/ArmLib: Add ArmReadIdIsar0() helper - MdePkg/BaseRngLib: Rename ArmReadIdIsar0() to ArmGetFeatRng() V5: - Removed references in Trnglib.h to 'Special Publication' 800-90A and 800-90C, and only reference 'Arm True Random Number Generator Firmware, Interface 1.0' in the Arm implementation of the TrngLib. [Jiewen] V4: - Removed dependencies on ArmPkg and dropped patch: [PATCH v3 12/22] SecurityPkg: Update Securitypkg.ci.yaml [Jiewen] - Use a dynamically allocated array to hold available algorithms. The array is freed in a new UNLOAD_IMAGE function and allocated in arch specific implementations of GetAvailableAlgorithms(), available in AArch64/AArch64Algo.c and Arm/ArmAlgo.c. - Correctly reference gEfiRngAlgorithmSp80090Ctr256Guid Guid by copying its address (add missing '&'). [Jiewen] V3: - Address Leif's comment (moving definitions, optimizations, ...) - Add ArmMonitorLib to choose Hvc/Smc conduit depending on a Pcd. - Re-factor some parts of SecurityPkg/RngDxe/ to ease the addition of new algorithms. - Add ArmHasRngExt() function to check Arm's FEAT_RNG extension. V2: - Updates TrngLib definitions to use RETURN_STATUS as the return type from the interface functions as TrngLib is base type library. - Drops the patch "MdePkg: Add definition for NULL GUID" as there is already an equivalent definition provided by gZeroGuid. Thus, the use of gNullGuid has been replaced with gZeroGuid.
