12 OMAP platforms(like OMAP3530) include DSP or other co-processors
13 for media acceleration. when carving out memory for the
14 accelerators we can end up creating a hole in the memory map
16 <kernel memory><hole(memory for accelerator)><kernel memory>
18 To handle such a memory configuration ARCH_HAS_HOLES_MEMORYMODEL
19 has to be enabled. For further information refer discussion at:
