Device initialization may require use of generic services such as starting up power rails, some of which may be controlled by GPIOs on an external controller that can't be used until full kernel services are available. Generic services can check k_is_in_isr() and mediate their behavior that way, but currently have no way to determine that the kernel is not available. Provide a function that indicates whether initialization is still in pre-kernel stages where no kernel services are available. Signed-off-by: Peter A. Bigot <pab@pabigot.com> |
