Subject: [PATCH v2 1/9] remoteproc: qcom_q6v5_mss: Introduce need_pas_mem_setup
Date: Wed, 31 Dec 2025 03:29:28 +0100 [thread overview]
Message-ID: <20251231-mss-v2-1-ae5eafd835c4@mainlining.org> (raw)
In-Reply-To: <20251231-mss-v2-0-ae5eafd835c4@mainlining.org>
Some platforms like MSM8953 and MSM8937 TZ needs to be
informed of the modem start address and pas_id.
Lets introduce need_pas_mem_setup flag for handle this case.
