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. |

Support for Broadcom BCM470X and BCM5301X SoCs with ARM CPU cores. |
|
|
|
This is a network SoC line mostly used in home routers and |
|
wifi access points, its internal name is Northstar. |
|
This includes the following SoC: BCM53010, BCM53011, BCM53012, |
|
BCM53014, BCM53015, BCM53016, BCM53017, BCM53018, BCM4707, |
|
BCM4708 and BCM4709. |
|
|
|
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 |
