Subjectdma_declare_coherent_memory on main memory
Hi all,

the ARM imx27/31 ports and various sh boards use
dma_declare_coherent_memory on main memory taken from the memblock

Is there any good reason these couldn't be switched to CMA areas?
Getting rid of these magic dma_declare_coherent_memory area would
help making the dma allocator a lot simpler.
