You should be able to sidestep this issue in the short term.  As long
as you can get the of_platform_populate() function to create
omap_devices that look identical to the current statically allocated
omap_devices.  If you need to extend the auxdata structure to do so,
then I'm okay with that.  You could add special handling for devices
compatible with "ti,omap3-device" or "ti,omap4-device".

I'm keen to see this done, and if you can put it together quickly,
then I think I still have time to queue it up for v3.1 (especially
since it would be a new block of code that should not break any
existing boards).
