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

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