-* Renesas SMP SRAM
-
-Renesas R-Car Gen2 and RZ/G1 SoCs need a small piece of SRAM for the jump stub
-for secondary CPU bringup and CPU hotplug.
-This memory is reserved by adding a child node to a "mmio-sram" node, cfr.
-Documentation/devicetree/bindings/sram/sram.txt.
-
-Required child node properties:
-  - compatible: Must be "renesas,smp-sram",
-  - reg: Address and length of the reserved SRAM.
-    The full physical (bus) address must be aligned to a 256 KiB boundary.
-
-
-Example:
-
-       icram1: sram@e63c0000 {
-               compatible = "mmio-sram";
-               reg = <0 0xe63c0000 0 0x1000>;
-               #address-cells = <1>;
-               #size-cells = <1>;
-               ranges = <0 0 0xe63c0000 0x1000>;
-
-               smp-sram@0 {
-                       compatible = "renesas,smp-sram";
-                       reg = <0 0x10>;
-               };
