This enables support for systems based on Broadcom IPROC architected SoCs.
The IPROC complex contains one or more ARM CPUs along with common
core periperals. Application specific SoCs are created by adding a
uArchitecture containing peripherals outside of the IPROC complex.
Currently supported SoCs are Cygnus.
