Subject: [PATCH 2/2] venus: firmware: Set virtual address ranges
Date: Thu, 9 Jul 2020 14:58:29 +0300 [thread overview]
Message-ID: <20200709115829.8194-3-stanimir.varbanov@linaro.org> (raw)
In-Reply-To: <20200709115829.8194-1-stanimir.varbanov@linaro.org>
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.
