ARM 11MP, Cortex-A5 and Cortex-A9 are often associated with a per-core
|
|
Timer-Watchdog (aka TWD), which provides both a per-cpu local timer
|
|
and watchdog.
|
|
|
|
The TWD is usually attached to a GIC to deliver its two per-processor
|
|
interrupts.

If present, the timer is powered through an always-on power domain,
|
|
therefore it never loses context.
