| config RAM |
| bool "Enable RAM drivers using Driver Model" |
| depends on DM |
| help |
| 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 |
| detected. |

| config SPL_RAM |
| bool "Enable RAM support in SPL" |
| depends on RAM && SPL_DM |
| help |
| 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. |

| config STM32_SDRAM |
| bool "Enable STM32 SDRAM support" |
| depends on RAM |
| help |
| STM32F7 family devices support flexible memory controller(FMC) to |
| support external memories like sdram, psram & nand. |
| This driver is for the sdram memory interface with the FMC. |

| config MPC83XX_SDRAM |
| bool "Enable MPC83XX SDRAM support" |
| depends on RAM |
| help |
| Enable support for the internal DDR Memory Controller of the MPC83xx |
| family of SoCs. Both static configurations, as well as configuring |
| the RAM through the use of SPD (Serial Presence Detect) is supported |
| via device tree settings. |

| config K3_AM654_DDRSS |
| bool "Enable AM654 DDRSS support" |
| depends on RAM && SOC_K3_AM6 |
| help |
| K3 based AM654 devices has DDR memory subsystem that comprises |
| Synopys DDR controller, Synopsis DDR phy and wrapper logic to |
| intergrate these blocks into the device. This DDR subsystem |
| provides an interface to external SDRAM devices. Enabling this |
| config add support for the initialization of the external |
| SDRAM devices connected to DDR subsystem. |
