Yes - Notice that it's not something new Thomas is introducing, it has
been in the tree for a long time (Ulf afaik added it).

I think I would actually prefer having all defconfigs together in
something like configs/ just like the Linux kernel has it instead of
spread over the tree. That has a number of advantages:

 - %_defconfig rule gets a lot simpler - E.G. something like:
%_defconfig: $(TOPDIR)/config/%_defconfig:
             cp $^ $(TOPDIR)/.config

 - We could display the available defconfigs in make help:
         @$(foreach b, $(notdir $(wildcard $(TOPDIR)/configs/*_defconfig)), \
          printf "  %-22s - Build for %s\\n" $(b) $(subst _defconfig,,$(b));)

 - It's easy to build all defconfigs before a release with simple shell
   scripting, and it's easy for newcomers to see what configs are
   available

The disadvantage is that the defconfig isn't together with the other
target/device/* files.

I implemented something like that for the company I work for, but Ulf
added the current implementation before I got mine committed.

Comments, anyone?
