12description:
13  The dynamic memory manager (DMM) is a module located immediately in front of
14  the SDRAM controllers (called EMIFs on OMAP). DMM manages various aspects of
15  memory accesses such as priority generation amongst initiators, configuration
16  of SDRAM interleaving, optimizing transfer of 2D block objects, and provide
17  MMU-like page translation for initiators which need contiguous dma bus
18  addresses.
