meta-phosphor: Make image-overlay an optional feature

Previously, added "overlay" to the IMAGE_FSTYPES
but this only has meaning if the 'image-overlay' class is used.  The
obmc-phosphor-image class explicitly includes 'image-overlay' when
appropriate but no other images (ie. ones that come with yocto) do.

Changed obmc-bsp-common to instead enable an obmc-phosphor-image feature
by setting OBMC_PHOSPHOR_IMAGE_OVERLAY=1. Then in obmc-phosphor-image we
add "overlay" to the IMAGE_FSTYPES only when the feature is enabled.

This will fix both non-phosphor images on hardware platforms and all images
on simulation platforms.

Build Status


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
