Please  be  careful  when  planning  for  this.  One  feature  thatis
essential  to  me is that it must be possible to have all information
for the configuration of a certain board in  a  single  configuration
file   (i.   e.   something   corresponding   to   what  we  have  in
include/config/<board>.h now)

Again, be careful. Ther eis a lot of #ifdef and Makefile trickery  in
handling the CONFIG_ and CFG_ definitions, and if you try to approach
this  with  a script, then it will *not* be a simple one. Also, "lots
of small files" is something that probably is not an improvement.

Indeed, please don't forget that you have to run  a  full  regression
test cycle on each and everyone board.

Maybe there is a somewhat  less  perfect,  but  simpler  approach  to
implement only a 90% or 95% solution with much less effort?

Best regards,
