* copyright-checker: Add FreeRTOS Arm collab copyright FreeRTOS Arm collab files shall have both Amazon's and Arm's copyright headers. Hence, the copyright checker is modified to check for both copyrights. Signed-off-by: Gaurav Aggarwal <aggarg@amazon.com> * armv8-m: Add support for IAR with TFM FREERTOS PORT As the case for ARMClang, and GCC toolchains, IAR with TFM FreeRTOS Port support is added. Signed-off-by: Ahmed Ismail <Ahmed.Ismail@arm.com> * armv8-m: Do not overwrite Control register value The current ARMv8-M FreeRTOS-Kernel Port code implementation is modified in a way that allows the CONTROL register's value to be retained rather than being overwritten. This is needed for adding PACBTI support as the special-purpose CONTROL register `PAC_EN`, `UPAC_EN`, `BTI_EN`, and `UBTI_EN` PACBTI enablement bits should be configured before calling `vRestoreContextOfFirstTask()` function which currently overwrite the value inside the CONTROL register. Signed-off-by: Ahmed Ismail <Ahmed.Ismail@arm.com> * armv8.1-m: Add PACBTI support to kernel non-secure implementation In this commit, Pointer Authentication, and Branch Target Identification Extension (PACBTI) support is added for Non-Secure and Non-TrustZone variants of Cortex-M85 FreeRTOS-Kernel Port. The PACBTI support is added for Arm Compiler For Embedded, and IAR toolchains only. The support in the kernel is not yet enabled for GNU toolchain due to known issues.

Each real time kernel port consists of three files that contain the core kernel components and are common to every port, and one or more files that are specific to a particular microcontroller and/or compiler. + The FreeRTOS/Source/Portable/MemMang directory contains the five sample memory allocators as described on the https://www.FreeRTOS.org WEB site. + The other directories each contain files specific to a particular microcontroller or compiler, where the directory name denotes the compiler specific files the directory contains. For example, if you are interested in the [compiler] port for the [architecture] microcontroller, then the port specific files are contained in FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the only port you are interested in then all the other directories can be ignored.
