This information is very useful to a customer and doesn't add much as
far as output.  No newlines at least.  The output also prints
information which is configurable.  I think giving the user feedback
about how they have the board configured is useful.

We have the standard Freescale DDR printf's turned into debug as that is
much, much more verbose than the output above.

Will fix.

This information is also very useful to a customer.

What are you referring to as far as "Alignment not by TAB"?

Everyone's config file breaks the 80 column rule, is this really
necessary to change?  I think splitting it up makes an already confusing
define even more confusing.
