[Ltib] slightly different kernel configs for subplatforms?

[Gernot Hillier]

Hi there!

I'm again working on integrating a slightly different mpc837x platform
into LTIB mainline.

There are three subtypes for this platform (mpc8377/8/9) with slightly
different kernel configurations (two are identical, the third differs in
three kernel options).

Now I wonder if there's a more elegant solution than adding the same
35kB of linux-...config to config/platform/xxx three times with only
slight modifications.

Is there a (simple) possibility to have diffs applied to the kernel
config or to modify kernel configuration manually in the spec file for a
certain platform?

TIA!
