+Broadcom Secure Monitor Bounce buffer
+-----------------------------------------------------
+This binding defines the location of the bounce buffer
+used for non-secure to secure communications.
+
+Required properties:
+- compatible : "bcm,kona-smc"
+- reg : Location and size of bounce buffer
+
+Example:
+	smc at 0x3404c000 {
+		compatible = "bcm,bcm11351-smc", "bcm,kona-smc";
+		reg = <0x3404c000 0x400>; //1 KiB in SRAM
+	};
