From: Krzysztof Kozlowski
Date: Mon Oct 21 2019 - 12:14:13 EST


The Renesas SRAM bindings list only compatible so integrate them into
generic SRAM bindings schema.

-* 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>;
- };
- };
