| 2 | ================================ |
| 3 | |
| 4 | The below desribes the physical memory layout for Marvell's Armada-8k SoC's. |
| 5 | |
| 6 | This assumes that the SoC includes Dual CP configuration, in case the flavor is using |
| 7 | a single CP configuration, then all secondary-CP mappings are invalid. |
| 8 | |
| 9 | All "Reserved" areas below, are kept for future usage. |
