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>;
|
|
};
|
|
};
