Subject: [PATCH v2 1/6] ARM: i.MX6QDL: add imxcfg helper to configure the TZASC1/2
Date: Thu, 26 Jun 2025 16:45:22 +0200 [thread overview]
Message-ID: <20250626144527.416697-2-m.felsch@pengutronix.de> (raw)
In-Reply-To: <20250626144527.416697-1-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.
