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