With ARCH_HAS_DECOMP_WDOG removed from arch/arm/boot/compressed/decompress.c,
all the arch_decomp_wdog() definition at platform level is unneeded.
Remmove it.

Enable GPIO and pinctrl in Kconfig.

Add required <mach/gpio.h> for gpiolib.

Instantiate the BCM2835 GPIO module in bcm2835.dtsi.

Add a pinctrl definition to bcm2835-rpi-b.dts that sets up all of the
board's required pinmux configuration. GPIO aren't specified; that's
left to gpio_request().

The BCM2835 is an ARM SoC from Broadcom. This patch adds very basic
support for this SoC.

http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf

Note that the documentation in the latter .pdf assumes the MMU setup
that's used on the "VideoCore" companion processor, and does not document
physical peripheral addresses. Subtract 0x5e000000 to obtain the physical
addresses. This is accounted for by the ranges property in the /soc node
in the device tree.

The BCM2835 SoC is used in the Raspberry Pi. This patch also adds a
minimal device tree for this board; enough to see some very early kernel
boot messages through earlyprintk. However, this patch does not yet
provide a useful booting system.

This patch was extracted from git://github.com/lp0/linux.git branch
rpi-split from 3-4 months ago, and significantly stripped down and
modified since.
