Tuomas Tynkkynen 36f4a8a485 sd-image-armv7l-multiplatform.nix: Preliminary Raspberry Pi 2/3 support
- RPi3 successfully gets to U-Boot, but then fails to boot the kernel
  due to a missing device tree file. This should get added to the 4.8
  kernel release once this patch is merged: https://lkml.org/lkml/2016/6/1/841
- RPi2 is not tested, but it should successfully boot the NixOS image.
