Or maybe it should, but then we are doing wrong things for other boards, particularly for the i.MX family. We have this node in the -u-boot.dtsi file for various other boards: git grep "linaro,optee-tz" -- '*-u-boot.dtsi' arch/arm/dts/imx8mm-u-boot.dtsi: compatible =3D "lin= aro,optee-tz"; arch/arm/dts/imx8mn-u-boot.dtsi: compatible =3D "lin= aro,optee-tz"; arch/arm/dts/imx8mp-debix-model-a-u-boot.dtsi: compatible = =3D "linaro,optee-tz"; arch/arm/dts/imx8mp-navqp-u-boot.dtsi: compatible =3D "lin= aro,optee-tz"; arch/arm/dts/imx8mp-u-boot.dtsi: compatible =3D "lin= aro,optee-tz"; arch/arm/dts/imx91-11x11-evk-u-boot.dtsi: compatible = =3D "linaro,optee-tz"; arch/arm/dts/imx91-11x11-frdm-u-boot.dtsi: compatible = =3D "linaro,optee-tz"; arch/arm/dts/imx91-93-phyboard-segin-common-u-boot.dtsi: = compatible =3D "linaro,optee-tz"; arch/arm/dts/imx93-11x11-evk-u-boot.dtsi: compatible = =3D "linaro,optee-tz"; arch/arm/dts/imx93-11x11-frdm-u-boot.dtsi: compatible = =3D "linaro,optee-tz"; arch/arm/dts/imx93-9x9-qsb-u-boot.dtsi: compatible =3D "lin= aro,optee-tz"; arch/arm/dts/imx93-kontron-bl-osm-s-u-boot.dtsi: com= patible =3D "linaro,optee-tz"; arch/arm/dts/imx93-var-som-symphony-u-boot.dtsi: com= patible =3D "linaro,optee-tz"; arch/arm/dts/stm32mp157a-dk1-u-boot.dtsi: compatible = =3D "linaro,optee-tz"; arch/arm/dts/stm32mp157c-ed1-u-boot.dtsi: compatible = =3D "linaro,optee-tz"; Thanks, Mathieu --=20 Mathieu Dubois-Briand, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
