init: Allow options to be fixed at build time

If the file /init-options exists copy it to the runtime location
/run/initramfs/init-options.

This allows an initramfs image to be built that will not parse
any u-boot or command line variables by adding a file into the
the image.  This can be done either through a recipe overlay or
additonal package today and could also be a cpio merged into the
initrd in the future.

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
