   1 Rockchip SRAM for smp bringup:
   2 ------------------------------
   3
   4 Rockchip's smp-capable SoCs use the first part of the sram for the bringup
   5 of the cores. Once the core gets powered up it executes the code that is
   6 residing at the very beginning of the sram.
   7
   8 Therefore a reserved section sub-node has to be added to the mmio-sram
   9 declaration.
  10
  11 Required sub-node properties:
  12 - compatible : should be "rockchip,rk3066-smp-sram"
  13
  14 The rest of the properties should follow the generic mmio-sram discription
  15 found in Documentation/devicetree/bindings/sram/sram.txt

  17 Example:
  18
  19         sram: sram@10080000 {
  20                 compatible = "mmio-sram";
  21                 reg = <0x10080000 0x10000>;
  22                 #address-cells = <1>;
  23                 #size-cells = <1>;
  24                 ranges;
  25
  26                 smp-sram@10080000 {
  27                         compatible = "rockchip,rk3066-smp-sram";
  28                         reg = <0x10080000 0x50>;
  29                 };
  30         };
