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?

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