Merge tag 'arm-soc/for-3.19/cygnus-platform-v2' of http://github.com/brcm/linux into next/soc

Pull "Broadcom Cygnus SoC platform support" from Florian Fainelli:

This pull request contains the platform code to support the Broadcom Cygnus SoC
using the iProc architecture:

- add support for the Broadcom Cygnus SoC
- consolidate the BCM5301X Kconfig options under the iProc menuconfig entry
- remove one level of menu in menuconfig

* tag 'arm-soc/for-3.19/cygnus-platform-v2' of http://github.com/brcm/linux:
  ARM: mach-bcm: ARCH_BCM_MOBILE: remove one level of menu from Kconfig
  ARM: mach-bcm: Consolidate currently supported IPROC SoCs
  ARM: cygnus: Initial support for Broadcom Cygnus SoC
