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
