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@0x3404c000 {

		compatible = "bcm,bcm11351-smc", "bcm,kona-smc";

		reg = <0x3404c000 0x400>; //1 KiB in SRAM

	};
