The current implementation is suboptimal. Let's rework it later in
common arch/arm code.
Use it to figure out whether we need to issue cache maintenance
Introduce a utility function to check whether a device is dma coherent.
The current implementation is suboptimal. Let's rework it later in
common arch/arm code.
Use it to figure out whether we need to issue cache maintenance
operations instead of checking on the existence of a particular dma_ops
