-flags can be ORed together and are:
-
-- DMA_MEMORY_EXCLUSIVE - only allocate memory from the declared regions.
-  Do not allow dma_alloc_coherent() to fall back to system memory when
-  it's out of memory in the declared region.

 As a simplification for the platforms, only *one* such region of
 memory may be declared per device.
