+ 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.
