Ian Lepore e56e554106 Add busdma sync ops before reading and after modifying the descriptor rings. ... This was previously working by accident because BUSDMA_COHERENT_MEMORY has always been set to strongly-ordered on arm. Now we're moving towards normal-uncacheable (what might be called write-combining on other platforms) and using the proper sync ops will be more important. Of course, that opens the question of just what is the "proper" sync op for shared concurrent dma access as opposed to accesses where the handoff of control of the memory has well-defined sequence points that match the available busdma sync operations.		2014-11-24 16:12:11 +00:00
