- * Name: up_idle
- *
- * Description:
- *   up_idle() is the logic that will be executed when their is no other
- *   ready-to-run task.  This is processor idle time and will continue until
- *   some interrupt occurs to cause a context switch from the idle task.
- *
- *   Processing in this state may be processor-specific. e.g., this is where
- *   power management operations might be performed.
