[PATCH] media: venus: core: Set up secure memory ranges for SC7180

Posted by Konrad Dybcio 2 years, 7 months ago

Not all SC7180 devices ship with ChromeOS firmware. WoA devices use
Android-like TZ, which uses 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 SC7180 devices.

This does indeed bring up the venus for me now. Thanks!
