Allwinner SRAM for smp bringup:

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

Allwinner's A80 SoC uses part of the secure sram for hotplugging of the

primary core (cpu0). Once the core gets powered up it checks if a magic

value is set at a specific location. If it is then the BROM will jump

to the software entry address, instead of executing a standard boot.

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

declaration.

Note that this is separate from the Allwinner SRAM controller found in

../../sram/sunxi-sram.txt. This SRAM is secure only and not mappable to

any device.

Also there are no "secure-only" properties. The implementation should

check if this SRAM is usable first.

Required sub-node properties:

- compatible : depending on the SoC this should be one of:

		"allwinner,sun9i-a80-smp-sram"

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

found in ../../misc/sram.txt

Example:

	sram_b: sram@20000 {

		/* 256 KiB secure SRAM at 0x20000 */

		compatible = "mmio-sram";

		reg = <0x00020000 0x40000>;

		#address-cells = <1>;

		#size-cells = <1>;

		ranges = <0 0x00020000 0x40000>;

		smp-sram@1000 {

			/*

			 * This is checked by BROM to determine if

			 * cpu0 should jump to SMP entry vector

			 */

			compatible = "allwinner,sun9i-a80-smp-sram";

			reg = <0x1000 0x8>;

		};
