It is the kernel's meta data that I'm talking about (the .scc and .cfg
files that make up how to patch and configure the BSP).
You can find details about the components in the Yocto mega manual (it
does a better job that I can do here).

Unless you've provided a .scc file that matches for the machine you
are building, the kernel configuration has no where to start when
looking for the standard set of configuration fragments.

Cheers,

Bruce
