  Not all SC7280 devices ship with ChromeOS firmware. Other devices need
PAS for image authentication. That requires the predefined virtual
address ranges to be passed via scm calls. Define them to enable Venus
on non-CrOS SC7280 devices.

Hi Hans,

Is there anything missing for this to be applied or could you pick this
up for v6.8?

Regards
Luca

Mauro, this series looks ready to be picked up. Can you please merge

Thanks,
