| 5 | This allows drivers to be provided for SDRAM and other RAM |
| 6 | controllers and their type to be specified in the board's device |
| 7 | tree. Generally some parameters are required to set up the RAM and |
| 8 | the RAM size can either be statically defined or dynamically |
| 9 | detected. |

| 15 | The RAM subsystem adds a small amount of overhead to the image. |
| 16 | If this is acceptable and you have a need to use RAM drivers in |
| 17 | SPL, enable this option. It might provide a cleaner interface to |
| 18 | setting up RAM (e.g. SDRAM / DDR) within SPL. |
