Hi,
This is follow-up for Christoph complain 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.
