This PR makes the following improvements to the ARM_CRx_No_GIC port- 1. Remove inline assembly and move all the assembly code to the portASM.S file. 2. Add support for configUSE_TASK_FPU_SUPPORT - - When configUSE_TASK_FPU_SUPPORT is defined to 1, tasks are created without floating point context. Tasks that want to use floating point, need to call portTASK_USES_FLOATING_POINT(). This is the current behavior. - When configUSE_TASK_FPU_SUPPORT is defined to 2, each task is created with a floating point context. If left undefined, configUSE_TASK_FPU_SUPPORT defaults to 1 for backward compatibility. 3. The application writer can now implement vApplicationSVCHandler to handle the SVC calls raised within the application. SVC 0 is used for the yield kernel operation and the application can use all the SVC calls other than 0. Signed-off-by: kar-rahul-aws <karahulx@amazon.com> |
