These are normal merge conflicts, and usually trivial to resolve.

Rejected. I really want to be able to see everythin in one place and
file. This may become a long file, but then you know exactly where to
search.

Not so long ago you could run "grep foo Documentation/Configure.help"
in the Linux kernel tree to find out what  config  option  "foo"  was
about.  Try this in a current Linux kernel tree with it's zillions of
scattered   Kconfig   files   (including   all   the    Kconfig.char,
Kconfig.debug,      Kconfig.i386,      Kconfig.net,     Kconfig.scsi,
Kconfig.x86_64 and what else variants).

Please don't worry about such merge conflicts in  the  Makefile  -  I
never complaint about such merge conflicts when adding patches.

I reject this patch because it tries to fix a poroblem which does not
exist, and instead it makes the code much harder to maintain.

Why don't you use git?

> +include	board/*/board.mk

BTW: this approach is broken. It does not handle the case of vendor
directories like board/amcc/, board/esd/, etc.
