What is the idea behind the ha
SMAF CMA allocator implement helpers functions to allow SMAF
to allocate contiguous memory.
match() each if at least one of the attached devices have coherent_dma_mask
set to DMA_BIT_MASK(32).
For allocation it use dma_alloc_attrs() with DMA_ATTR_WRITE_COMBINE and not
dma_alloc_writecombine to be
