Does this mean you're looking at dropping the utils/amd-udi directory
as well?  This is some code to talk to a ROM monitor that was used
on 29k boards long ago, it's a code drop of AMD's own support code
slightly munged to work in our build setup.  Mostly, though, it's
1.4MB of wasted disk space on every gdb checkout these days.
