Yes, and they're not necessarily easy to find.

On appropriately designed and manufactured
boards, only.  So that's an optimistic upper
bound, not necessarily a sane default.

Also, not available to OpenOCD at this time
since we have neither a BSDL parser, or places
to store the information one would report.  It
ought to integrate with SVF and XSVF, as one
example I seem to recall:  pin/ball assignments
and all that stuff.

I don't think we should require folk to get and
use BSDL files for their chips, though I'd have
nothing against using that data if it were handy.

They can currently just read the files and put
that data into the chip config files (lots of
those config files were done that way).
