Introduce a new debug sysfs file, which accepts the following commands: ps - show task running in firmware banner - show startup banner get_root - get ROOT object heap - show heap statistics irq - show irq statistics semaphore - show semaphore status wiring - show wiring status get_object_by_name %s - get address for object get_fsm_by_name %s - get address for FSM dump_object %p - show information about object dump_objects - dump all objects (NOTE: will crash firmware) show_objects - show graph about all objects known get_debug_level - get debug level for object set_debug_level - set debug level for object set_debug_level_rec - set debug level recursive for all objects get_fsm_count - get count of FSM's get_fsm_by_index - get fsm address for index get_fsm_debug_level - get debug level for fsm set_fsm_debug_level - set debug level for fsm
