45	  Broadcom Northstar Plus family of SoCs are used for switching control
46	  and management applications as well as residential router/gateway
47	  applications. The SoC features dual core Cortex A9 ARM CPUs,
48	  integrating several peripheral interfaces including multiple Gigabit
49	  Ethernet PHYs, DDR3 memory, PCIE Gen-2, USB 2.0 and USB 3.0, serial and
50	  NAND flash, SATA and several other IO controllers.

57
58	  This is a network SoC line mostly used in home routers and
59	  wifi access points, it's internal name is Northstar.
60	  This inclused the following SoC: BCM53010, BCM53011, BCM53012,
61	  BCM53014, BCM53015, BCM53016, BCM53017, BCM53018, BCM4707,
62	  BCM4708 and BCM4709.
63
64	  Do not confuse this with the BCM4760 which is a totally
65	  different SoC or with the older BCM47XX and BCM53XX based
66	  network SoC using a MIPS CPU, they are supported by arch/mips/bcm47xx
