Witherspoon AVS Bus Control

Perform an AVS bus workaround on the VRMs attached
to the processor.  The AVS bus is how the processor
talks to the VRMs.

After the workaround, this also provides services to
disable the AVS bus so a VRM override can be run, and
then enable it again afterwards.

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
