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 && TPL
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_AM654
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_DDRSS
bool "Enable K3 DDRSS support"
depends on RAM
choice

config K3_J721E_DDRSS
bool "Enable J721E DDRSS support"
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 K3_AM64_DDRSS
bool "Enable AM64 DDRSS support"
help
The AM64 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 AM642 family of SoCs.
config K3_AM62A_DDRSS
bool "Enable AM62A DDRSS support"
help
The AM62A DDR subsystem comprises of a DDR controller, DDR PHY and
wrapper logic to integrate these blocks into once device. The DDR
subsystem is used to provide an interface to external SDRAM devices
which can be utilized for storing programs or any other data.
Enabling this option adds support for the DDR memory controller for
the AM62A 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.
