Subject: media: venus: core: Set up secure memory ranges for SC7280
Author: Luca Weiss <luca.we...@fairphone.com>
Date: Fri Dec 1 10:33:18 2023 +0100
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.
