Hello,

I am trying to run OPTEE-OS on i.MX6Q Sabre Automotive board.
I added following lines to imx6qdl-sabreauto.dtsi:

reserved-memory {
    #address-cells = <1>;
    #size-cells = <1>;
    ranges;

    optee@0x8D000000 {
        reg = <0x8D000000 0x03000000>;
    };
};

firmware {
    optee {
        compatible = "linaro,optee-tz";
        method = "smc";
    };
};

Kernel fails on invoke_fn(OPTEE_SMC_CALLS_UID, 0, 0, 0, 0, 0, 0, 0, &res);

I use signed u-boot and zImage, but I don't burn fuses. My boot security configuration is Open.
I need enable secure boot for running optee drivers? Or my dts file is wrong?
