 25           core periperals. Application specific SoCs are created by adding a
 26           uArchitecture containing peripherals outside of the IPROC complex.

 73 
 74           Do not confuse this with the BCM4760 which is a totally
 75           different SoC or with the older BCM47XX and BCM53XX based
 76           network SoC using a MIPS CPU, they are supported by arch/mips/bcm47xx
