I think we need to look harder at re-factoring drivers/core/ofnode.c to move the live portions elsewhere. It's 175 platforms out of 1489 using it today so we can probably do better. The very first thing I stumbled on is that OF_TRANSLATE might have incorrect deps? A quick glance at of_translate_dma_address / of_translate_address says to me it should all be optimized out in the not-OF_LIVE case. -- Tom
