Subject: [PATCH 04/14] ARM: i.MX6QDL: add imxcfg helper to configure the TZASC1/2
Date: Fri, 27 Jun 2025 16:07:50 +0200	[thread overview]
Message-ID: <20250627-arm-optee-early-helper-v1-4-4b098e8ac7cd@pengutronix.de> (raw)
In-Reply-To: <20250627-arm-optee-early-helper-v1-0-4b098e8ac7cd@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.
