  "message": "Arm-Cortex-R82: Add MPU support (#1347)\n\n* arm-cortex-r82: Add MPU support\n\nThis commit introduces support for the Memory Protection Unit (MPU)\nto the ARM Cortex-R82 port. The MPU enhances system security\nby allowing the definition of memory regions with specific access\npermissions. The following changes have been made:\n- Added MPU configuration functions in `port.c` to set up memory\n  regions and their attributes.\n- Updated `portASM.S` to include assembly routines for MPU\n  and context switching with MPU support.\n- Created `mpu_wrappers_v2_asm.c` to provide assembly wrappers for\n  MPU operations.\n- Updated `portmacro.h` to include MPU-related macros and definitions.\n- Modified `task.h` to include MPU-related task attributes.\n- Updated `CMakeLists.txt` to include the new MPU source file.\n- Enhanced the `README.md` with instructions on MPU configuration.\n\nSigned-off-by: Ahmed Ismail \u003cAhmed.Ismail@arm.com\u003e\n\n* cortex-r82: Minor code improvements\n\nThis commit includes minor code improvements to enhance readability\nand maintainability of the Cortex-R82 port files. Changes include\nrefactoring variable names, optimizing comments, and improving code\nstructure without altering functionality.\n\nSigned-off-by: Ahmed Ismail \u003cAhmed.Ismail@arm.com\u003e\n\n* tasks: Disable stack-depth check if MPU wrappers is set\n\nThis stack-depth check should not be performed for ports\nwhere portUSING_MPU_WRAPPERS is set to 1.\nIn this case, pxTopOfStack and pxNewTCB-\u003epxTopOfStack reside\nin different memory regions: pxTopOfStack is in unprivileged SRAM,\nwhile pxNewTCB-\u003epxTopOfStack is in privileged SRAM.\nThis is because pxPortInitialiseStack() returns the address of\n`ullContext` array rather than the decremented pxTopOfStack,\nas is done in the non-MPU case.\nConsequently, this check is not valid in this scenario.\n\nSigned-off-by: Ahmed Ismail \u003cAhmed.Ismail@arm.com\u003e\n\n---------\n\nSigned-off-by: Ahmed Ismail \u003cAhmed.Ismail@arm.com\u003e",
