+Amlogic Meson6/Meson8/Meson8b bootrom:
+--------------------------------------
+
+The bootrom register area can be used to access SoC specific
+information, such as the "misc version".
+
+Required properties:
+- reg: the register range of the bootrom registers
+- compatible: should be "amlogic,meson-mx-bootrom" along with "syscon"
+
+
+Example:
+
+	bootrom: bootrom@d9040000 {
+		compatible = "amlogic,meson-mx-bootrom", "syscon";
+		reg = <0xd9040000 0x10000>;
+	};
