In OpenWrt, we don't keep full kernel configurations in our target
config-* files. We have a generic config template, and the target config
file is supposed to contain only changes to the generic config template.
Merging and splitting is automated and scripted.
If you run make kernel_oldconfig, it will copy the config to the kernel
build dir, run make oldconfig in the kernel tree, then split the config
again and keep only the target specific bits.
The next step is then to go through the generated file by hand and throw
out any lines that change things relative to the OpenWrt default that
shouldn't really be changed for the target.
This keeps our target config files maintainable and makes it easy for us
to change defaults for all targets as well.
