This commit adds a CMakeLists.txt file for Arm Cortex-M33. Signed-off-by: Kevin Townsend <kevin.townsend@linaro.org> Signed-off-by: Jimmy Brisson <jimmy.brisson@linaro.org>
There exist some platforms, such as the MPS3-AN524, that are Cortex-M33 and do not have any floating point unit. Previously, the assembler would error on these targets. Signed-off-by: Jimmy Brisson <jimmy.brisson@linaro.org>

Hi @microbuilder - thanks for bringing this up! We'll fix this internally and it'll be in our next release. |

Update: arm-none-eabi.cmake and tx_thread_schedule.S have been fixed internally and will be available in our next release, scheduled for August 2. At this time, we are not going to add/maintain new cmake files. |

This commit enables support for the Arm Cortex-M33, using the GNU toolchain. By default, HW DSP or FP support has been disabled, and compilation takes place with
-mfloat-abi=softfp.It also address an issue with
tx_thread_schedule.Swhere floating point instructions were being hard-coded into the assembly code, causing a fault on devices that don't have HW FPU support, such as the MPS3 AN524 Core 0, etc.Signed-off-by: Kevin Townsend kevin.townsend@linaro.org
