Why are all these things named ARCH_*?

I think the we should have only  ARCH_PPC  and  ARCH_ARM.  The  other
things you mentioned so far are not architecture specific - they were
related to CPUs, boards, configurations, ...

Ummm... I see what you mean. I guess  I'd  have  to  see  a  complete
working example first.

But that means that the configuration for one  board  is  distributed
over  3 (or more?) config.in files. It has certain advantages to have
it concentrated in one place...

I disagree. It is much more complicated to find  all  config  options
relevant  to  once  specific  system,  and  requires  a  much  better
understanding  of  the  config  mechanism  to   add   a   new   board
configuration - correctly, that is.
