* Armv8-M: Formatting changes Signed-off-by: Devaraj Ranganna <devaraj.ranganna@arm.com> * Armv8-M: Add support for interrupt priority check FreeRTOS provides `FromISR` system calls which can be called directly from interrupt service routines. It is crucial that the priority of these ISRs is set to same or lower value (numerically higher) than that of `configMAX_SYSCALL_INTERRUPT_PRIORITY`. For more information refer to https://www.FreeRTOS.org/RTOS-Cortex-M3-M4.html. Add a check to trigger an assert when an ISR with priority higher (numerically lower) than `configMAX_SYSCALL_INTERRUPT_PRIORITY` calls `FromISR` system calls if `configASSERT` macro is defined. In addition, add a config option `configQEMU_DISABLE_INTERRUPT_PRIO_BITS_CHECK` to disable interrupt priority check while running on QEMU. Based on the discussion https://gitlab.com/qemu-project/qemu/-/issues/1122, The interrupt priority bits in QEMU do not match the real hardware. Therefore the assert that checks the number of implemented bits and __NVIC_PRIO_BITS will always fail. The config option `configQEMU_DISABLE_INTERRUPT_PRIO_BITS_CHECK` should be defined in the `FreeRTOSConfig.h` for QEMU targets.
