Currently it's not possible to authenticate additional boot images in HAB open configuration.
The hab.c code is checking if the SEC_CONFIG[1] fuse is programmed prior to calling the hab_authenticate_image() API function. Users cannot check if their additional boot images has been correctly signed prior to closing their device.
Enable hab.c to authenticate additional boot images in open mode so HAB events can be retrieved through get_hab_status() function.
