Tiler support is not yet in OMAP builds. So multi-omap build will NOT break, but would exclude VRFB feature in the build.

Building a multi-omap kernel is not impacted as long as the 

display is not choosen in the build.  Usually display is 
chosen from the board file.

So you are saying it *IS* broken when wanting vrfb on omap3 
and tiler on omap4, right?

Exclude VRFB from OMAP4 onwards and include only for
OMAP2 and OMAP3 builds.  In OMAP4 VRFB HW IP is replaced
with a new HW IP "TILER"

How does this work for multi-omap kernels, e.g. building a 
kernel with beagle and panda support?
