Subject: [PATCH v2 04/14] ARM: i.MX6QDL: add imxcfg helper to configure the TZASC1/2
Date: Mon, 30 Jun 2025 09:45:46 +0200 [thread overview]
Message-ID: <20250630-arm-optee-early-helper-v2-4-c8cce3ae42b0@pengutronix.de> (raw)
In-Reply-To: <20250630-arm-optee-early-helper-v2-0-c8cce3ae42b0@pengutronix.de>
From: Marco Felsch <m.felsch@pengutronix.de>
On i.MX6 platforms we need to set the bypass mode within the DCD unlike
the i.MX8M platforms which uses the PBL lowlevel code
(imx8m_tzc380_init()).
Add a helper for this to make the integration easier.
