Igal was working on adding ARM64 support when this patch was created, thus the
choice of #ifdef CONFIG_ARM64. Unifying this for PPC and ARM64 by always calling
of_platform_populate() sounds like the best approach. I would need to synchronize
the introduction of this code with the removal of the fsl,fman entry from the
of_device_ids[] array.

Dave, Michael, Scott, is it ok to add to v2 of this patch set the patch that removes
the compatible "fsl,fman" from arch/powerpc/platforms/85xx/corenet_generic.c?

Thanks,
Madalin
