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. | |

14 | help |
| 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. | |

| 38 | bool "Enable MPC83XX SDRAM support" | |
| 39 | depends on RAM | |
| 40 | help | |
| 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. | |

46 | config K3_AM654_DDRSS |
| 47 | bool "Enable AM654 DDRSS support" | |
| 48 | depends on RAM && SOC_K3_AM6 | |
| 49 | help | |
| 50 | K3 based AM654 devices has DDR memory subsystem that comprises | |
| 51 | Synopys DDR controller, Synopsis DDR phy and wrapper logic to | |
| 52 | intergrate these blocks into the device. This DDR subsystem | |
| 53 | provides an interface to external SDRAM devices. Enabling this | |
| 54 | config add support for the initialization of the external | |
| 55 | SDRAM devices connected to DDR subsystem. | |

| 59 | depends on RAM | |
| 60 | help | |
| 61 | The J721E DDR subsystem comprises DDR controller, DDR PHY and | |
| 62 | wrapper logic to integrate these blocks in the device. The DDR | |
| 63 | subsystem is used to provide an interface to external SDRAM | |
| 64 | devices which can be utilized for storing program or data. | |
| 65 | Enabling this config adds support for the DDR memory controller | |
| 66 | on J721E family of SoCs. | |
