* 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>;
|
||||
};
|
||||
};
