Merge tag 'arm-soc/for-4.2/soc-part2' of http://github.com/broadcom/stblinux into next/soc
Merge "changes for Broadcom SoCs":
- Dan fixes an error path in the BCM63xx SMP code
- Ray adds the relevant Kconfig selects to enable the Broadcom NAND driver on Cygnus
- Kevin provides a change to the Broadcom GISB arbiter driver to make it work with
MIPS-based big-endian STB SoCs (this was a long-standing change that had dependencies on
code in drivers/of/*)
- Gregory enables the use of GPIOLIB for brcmstb SoCs and bumps the number of GPIOs for
these platforms
