- 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 TPL_RAM
- bool "Enable RAM support in TPL"
- depends on RAM
- 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
- TPL, enable this option. It might provide a cleaner interface to
- setting up RAM (e.g. SDRAM / DDR) within TPL.
- 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.
- config K3_J721E_DDRSS
- bool "Enable J721E DDRSS support"
- depends on RAM
- help
- The J721E DDR subsystem comprises DDR controller, DDR PHY and
- wrapper logic to integrate these blocks in the device. The DDR
- subsystem is used to provide an interface to external SDRAM
- devices which can be utilized for storing program or data.
- Enabling this config adds support for the DDR memory controller
- on J721E family of SoCs.
- config IMXRT_SDRAM
- bool "Enable i.MXRT SDRAM support"
- depends on RAM
- help
- i.MXRT family devices support smart external memory controller(SEMC)
- to support external memories like sdram, psram & nand.
- This driver is for the sdram memory interface with the SEMC.
