Building an image

git clone --recursive git@github.com:open-power/op-build.git
cd op-build
. op-build-env
op-build palmetto_defconfig && op-build

This will build an image for a Palmetto system. There exists default configurations for other platforms in openpower/configs/ such as Habanero and Firestone.
