Tiler support is not yet in OMAP builds. So multi-omap build will NOT break, but would exclude VRFB feature in the build.
in which case, is'nt this patch redundant :) ?
joking apart, would'nt a set of function pointers be better - the
function pointers could be runtime initialized. the rotational functions
for Tiler OR vrfb could be used?

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?

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