> - select OF_DMA_DEFAULT_COHERENT if !NOT_COHERENT_CACHE Doesn't powerpc need to select CONFIG_ARCH_DMA_DEFAULT_COHERENT now, or even better should be doing that in the patch adding that symbol? In fact I wonder if adding CONFIG_ARCH_DMA_DEFAULT_COHERENT and removing OF_DMA_DEFAULT_COHERENT should be one patch, as that seems to bring over the intent a little better I'd say.
