Some time ago I wrote a little script that minimized a .config and
applied it to ns9xxx_defconfig.

The result is that ns9xxx_defconfig only has 79 lines while the average
is >1200.  (I have to admit that ns9xxx isn't complete by far as there
are no device drivers in tree, but anyhow, after $(make
ns9xxx_defconfig) the resulting .config has 1181 lines.) Would it already
help to apply it to all defconfigs?  A nice effect is that changes to
these small files are smaller and so easier to understand.  IIRC I posted
the script to linux-kbuild back then.  I can try to find and apply it
before the next merge window.

And I want to point out that there are efforts to merge all arch-mx* and
plat-mxc and so reduce the number of defconfigs from seven[1] to one.
Eric picked up on the runtime-physoffset patches that are currently a
stopper for (AFAIK) several merges.

Best regards

[1] IIRC I recently saw a patch that adds mx25_defconfig, so there are
even eight imx defconfigs.
