Hello, The purpose of this patch set is to add hardware I/O Coherency support for Armada 370 and Armada XP. Theses SoCs come with an unit called coherency fabric. A beginning of the support for this unit have been introduced with the SMP patch set. This series extend this support: the coherency fabric unit allows to use the Armada XP and the Armada 370 as nearly coherent architectures.
The second patches enables this new feature and register our own set of DMA ops, to benefit this hardware enhancement. The first patch introduces a new flag for the address decoding configuration in order to be able to set the memory windows as shared memory. This series depend on the SMP patch set posted on Monday (http://thread.gmane.org/gmane.linux.ports.arm.kernel/194901).
