I've finished this today (all platforms plus some more details and 
changes) but wont' post it again. Instead who is interested can see it 
in my freedesktop git repo - people.freedesktop.org/~tursulin/drm-intel 
platform-kconfig - but for some reason it is not showing in GitWeb any 
longer.

Anyway.. with the latest build the i915.ko size goes from 15600073 to 
1256697 when I enable only Skylake via Kconfig. This is 296kiB and close 
to 20% saving.

Regards,

Tvrtko
