I tried port optee to customize board, but encouted panic and I could not figure it out. here is log and dree tree setting for the board, thank you

Fixed by adding 

/* Regulators */

    vdd: regulator-vdd {

        compatible = "regulator-fixed";

        regulator-name = "vdd";

        regulator-min-microvolt = <3300000>;

        regulator-max-microvolt = <3300000>;

        regulator-always-on;

    };

    vddcore: vddcore {

        compatible = "regulator-fixed";

        regulator-name = "vddcore";

        regulator-min-microvolt = <1200000>;

        regulator-max-microvolt = <1200000>;

        regulator-always-on;

    };

&cpu0{

    cpu-supply = <&vddcore>;

};

&cpu1 {

    cpu-supply = <&vddcore>;

};
