24 This enables support for systems based on Broadcom IPROC architected SoCs.
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.

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

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