Kernel, boot firmware, devices and hacks for Raspberry Pi

This script will run the following SlackBuilds:
  raspi-boot
  raspi-devs
  raspi-hacks
  kernel_raspi
  kernel-modules-raspi
  installer (if DOINSTALLER=yes)
  kernel-source-raspi (if DOSOURCE=yes)

Before running this script, you must set up the following git repos:

  git clone git://github.com/raspberrypi/linux.git \
            kernel_raspi/linux
  git clone git://github.com/raspberrypi/firmware.git \
            raspi-boot/firmware

Then you must checkout the branch for the kernel version that you want
to build, for example:

  cd kernel_raspi/linux
  git checkout -b rpi-3.12.y -t origin/rpi-3.12.y
  cd -
