Ahmed Ismail	3cca1ec00e	arm-cortex-r82: Add MPU support ... This commit introduces support for the Memory Protection Unit (MPU) to the ARM Cortex-R82 port. The MPU enhances system security by allowing the definition of memory regions with specific access permissions. The following changes have been made: - Added MPU configuration functions in `port.c` to set up memory regions and their attributes. - Updated `portASM.S` to include assembly routines for MPU and context switching with MPU support. - Created `mpu_wrappers_v2_asm.c` to provide assembly wrappers for MPU operations. - Updated `portmacro.h` to include MPU-related macros and definitions. - Modified `task.h` to include MPU-related task attributes. - Updated `CMakeLists.txt` to include the new MPU source file. - Enhanced the `README.md` with instructions on MPU configuration.

Ahmed Ismail	a8ae21c88e	armv8-r: Add Arm Cortex-R82 non-MPU port (#1289) ... The goal of this commit is to add the GCC/ARMClang non-MPU port variant for ARM Cortex-R82 processor which is ARMv8-R AArch64 based. The work done is inspired by the GCC ARM_AARCH64 FreeRTOS port. This port has the following features: * Uses single security state (non TrustZone). * Supports SMP (Symmetric multi-processing). * Doesn't support Hypervisor (EL2). * Doesn't support neither PMSA (MPU) nor VMSA (MMU).
