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

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

Broadcom Northstar Plus family of SoCs are used for switching control
|
and management applications as well as residential router/gateway
|
applications. The SoC features dual core Cortex A9 ARM CPUs,
|
integrating several peripheral interfaces including multiple Gigabit
|
Ethernet PHYs, DDR3 memory, PCIE Gen-2, USB 2.0 and USB 3.0, serial and

wifi access points, its internal name is Northstar.
|
This includes the following SoC: BCM53010, BCM53011, BCM53012,

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