The default values from Kconfig files are used
where CONFIG options are not specified by the defconfig.

So, I think corenet_basic_defconfig is a full defconfig
even if it contains a single CONFIG option.

Since the difference between "*_defconfig" and "*.config"
is ambiguous in some cases, it depends on the intended usage.

I do not know how it should be documented.
