[PATCH v2 2/2] venus: firmware: Set virtual address ranges

From: Stanimir Varbanov
Date: Mon Aug 17 2020 - 04:28:23 EST


In order to boot some of the new Venus firmware versions TZ call to set
virtual address ranges is needed. Add virtual address ranges for CP and
CP_NONPIX in resource structure and use them when loading and booting
the firmware on remote processor.
