Re-enable out of tree device trees

This snippet was mistakenly removed with 8ef9fee.

Note that this isn't a matter of policy, it simply enables
the option to do it.  The in-tree device tree is still the default.

This enables things like workbook or schematic generated device
trees.  It also addresses the inevitable fact that the upstream kernel
will probably not want device trees for every board in the world.

Build Status

Building

OpenBMC uses Yocto/Open-Embedded for a build system, which supports an out-of-tree build. It is recommended that you create an empty directory somewhere to hold the build. This directory will get big.

On Ubuntu 14.04 the following packages are required to build the default target

sudo apt-get install -y git build-essential libsdl1.2-dev texinfo gawk chrpath diffstat

On Fedora 23 the following packages are required to build the default target:

sudo dnf install -y git patch diffstat texinfo chrpath SDL-devel bitbake
sudo dnf groupinstall "C Development Tools and Libraries"

To start a build:

cd <builddir>
. <repodir>/openbmc-env
bitbake obmc-phosphor-image
