Rockchip SRAM for smp bringup:

------------------------------



Rockchip's smp-capable SoCs use the first part of the sram for the bringup

of the cores. Once the core gets powered up it executes the code that is

residing at the very beginning of the sram.



Therefore a reserved section sub-node has to be added to the mmio-sram

declaration.



Required sub-node properties:

- compatible : should be "rockchip,rk3066-smp-sram"



The rest of the properties should follow the generic mmio-sram discription

found in Documentation/devicetree/bindings/sram/sram.txt



Example:



	sram: sram@10080000 {

		compatible = "mmio-sram";

		reg = <0x10080000 0x10000>;

		#address-cells = <1>;

		#size-cells = <1>;

		ranges;



		smp-sram@10080000 {

			compatible = "rockchip,rk3066-smp-sram";

			reg = <0x10080000 0x50>;

		};

	};
