	  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.

	  Support for Broadcom Northstar Plus SoC.
	  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
	  NAND flash, SATA and several other IO controllers.
