Subject: [PATCH v4 0/2] Add generic OP-TEE loading for i.MX6
Date: Mon, 16 Feb 2026 11:36:22 +0100 [thread overview]
Message-ID: <20260216-v2025-11-0-topic-optee-imx6-start-v4-0-b73279a8a971@pengutronix.de> (raw)
Add a generic way to load OP-TEE from i.MX6 CPU's with config options
instead of board and lowlevel code.
If the generic i.MX6 OPTEE firmware gets enabled, it will be loaded
during boot, if the boardcode is using the imx6*_barebox_entry function
to start barebox instead of the generic barebox_arm_entry. These will
make sure, that OP-TEE is configured correctly and if the space for the
overlay is configured, they will also apply the devicetree overlay
provided by OP-TEE.
This is build upon the work of Marco for i.MX8M.
