System bringup is a complex and difficult task.  Modern hardware is
incredibly complex and it's not getting any simpler.  Bringup engineers
spend far too much time hunting through specs and register dumps, trying
to find the source of their problems.  There are very few tools available
to make this easier.

This paper introduces three open source tools that can help ease the
pain, and hopefully shorten bringup cycles for new platforms.  SGABIOS is
a legacy option ROM which implements a simple serial console interface for
BIOS.  Iotools is a suite of low-level utilities which enables rapid
prototyping of register settings.  Prettyprint is a powerful library and
toolset which allows users to easily examine and manipulate device settings.
