Jonas Bonn	7b903e6c02	openrisc: provide dma_map_ops ... This switches OpenRISC over to fully using the generic dma-mapping framework. This was almost already the case as the architecture's implementation was essentially a copy of the generic header. This also brings this architecture in line with the recent changes to dma_map_ops (adding attributes to ops->alloc). Signed-off-by: Jonas Bonn <jonas@southpole.se>	2012-05-08 11:43:51 +02:00
Jonas Bonn	707b38a00b	Add missing DMA ops ... For the initial architecture submission, not all of the DMA ops were implemented. This patch adds the *map_page and *map_sg variants of the DMA mapping ops. This patch is currently of interest mainly to some drivers that haven't been submitted upstream yet.
