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 Signed-off-by: Arnd Bergmann <arnd@arndb.de>
