I decided to create dma tag in ofwbus and moved 'dma-coherent' property to '/' node in DTS.
All changes related to dma tag creation are now done only if FDT is defined.
Yes, coherent IO is a platform-wide feature.
I added two comments to the code as you suggested. First one is different because DMAMAP_COHERENT flag does not disable sync ops. It only show that the buffer must be coherent.
