* ARM Snoop Control Unit (SCU)
As part of the MPCore complex, Cortex-A5 and Cortex-A9 are provided
with a Snoop Control Unit. The register range is usually 256 (0x100)
bytes.

- compatible : Should be:
"arm,cortex-a9-scu"
"arm,cortex-a5-scu"
"arm,arm11mp-scu"
- reg : Specify the base address and the size of the SCU register window.
Example:
scu@a0410000 {
compatible = "arm,cortex-a9-scu";
reg = <0xa0410000 0x100>;
};
