1 | config RAM |
| 2 | bool "Enable RAM drivers using Driver Model" | |
| 3 | depends on DM | |
| 4 | help | |
| 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. | |

| 30 | bool "Enable STM32 SDRAM support" | |
| 31 | depends on RAM | |
| 32 | help | |
| 33 | STM32F7 family devices support flexible memory controller(FMC) to | |
| 34 | support external memories like sdram, psram & nand. | |
| 35 | This driver is for the sdram memory interface with the FMC. | |

| 41 | Enable support for the internal DDR Memory Controller of the MPC83xx | |
| 42 | family of SoCs. Both static configurations, as well as configuring | |
| 43 | the RAM through the use of SPD (Serial Presence Detect) is supported | |
| 44 | via device tree settings. | |
