Revision Information
====================
May 18, 2005: Rev 0.1 - Initial draft, no chapter III yet.
May 19, 2005: Rev 0.2 - Add chapter III and bits & pieces here or
clarifies the fact that a lot of things are
optional, the kernel only requires a very
small device tree, though it is encouraged
to provide an as complete one as possible.
May 24, 2005: Rev 0.3
