* 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.
