Note that not all of the defined pad options are currently present
in these headers, including some that are being used by some down-stream 
boards:

I'm taking a look at the XML files distributed as a part of the
IOMux tool to see if they can be used to produce a more complete set.

I think a single patch or patch set to clean things up will save effort
in the long term instead of handling things on a pin-by-pin basis as
new boards are designed.
