From: Thiago Jung Bauermann <bauerman@linux.ibm.com>
|
|
|
|
There are other platforms which also have CPUs that start powered off, so
|
|
generalize the start-powered-off property so that it can be used by them.
|
|
|
|
Note that ARMv7MState also has a property of the same name but this patch
|
|
doesn't change it because that class isn't a subclass of CPUState so it
|
|
wouldn't be a trivial change.
|
|
|
|
This change should not cause any change in behavior.
