[PATCH 0/2] Introduce interface for default DMA pool

[vladimir.murzin@arm.com (Vladimir Murzin)]

Hi,

This is follow-up for Christoph complain [1] of overloading the current
dma coherent infrastructure with the global pool. To address that I
implemented Robin's idea of the new interface to the global pool and
wire up it with (only existent user) ARM NOMMU.  Since I have not
heard from Vitaly and/or George of their use of global pool, I'm
leaving ARM MMU part to them.

Changelog:
	RFC -> v1
	    - dropped RFC tag
	    - s/_from_coherent/_from_dev_coherent/g per Christoph
	    - added Tested-by from Andras
