Something is wrong here with authorship...
IMO, you should be the author,
and people above listed in derived from ... or something.

I would also, remove the postal address, as it may change
(and did in the past), but it is your call.

This should be done in board config file (see the README).
Also, after moving this to config file, I think, the include
for mach-types.h can be removed.

This is really a nice comment, but...
That is one of the reasons I like the whole thing done in a
function or an array rather than in a multi-line macro...

Some of these should not have a value, right?

Can't the above be inlined?
