 25           The IPROC complex contains one or more ARM CPUs along with common
 26           core periperals. Application specific SoCs are created by adding a
 27           uArchitecture containing peripherals outside of the IPROC complex.
 28           Currently supported SoCs are Cygnus.

 69           This is a network SoC line mostly used in home routers and
 70           wifi access points, it's internal name is Northstar.
 71           This inclused the following SoC: BCM53010, BCM53011, BCM53012,
 72           BCM53014, BCM53015, BCM53016, BCM53017, BCM53018, BCM4707,
 73           BCM4708 and BCM4709.
 74 
 75           Do not confuse this with the BCM4760 which is a totally
 76           different SoC or with the older BCM47XX and BCM53XX based
 77           network SoC using a MIPS CPU, they are supported by arch/mips/bcm47xx
