config MEMORY
	bool "Enable Driver Model for Memory Controller drivers"
	depends on DM
	help
	  Enable driver model for Memory Controller devices.
	  These devices provide Memory bus interface to various devices like
	  SRAM, Ethernet adapters, FPGAs, etc.
	  For now this uclass has no methods yet.

config ATMEL_EBI
	bool
	help
	  Driver for Atmel EBI controller. This is a dummy
	  driver. Doesn't provide an access to EBI controller. Select
	  this option to enable the NAND flash controller driver

config SANDBOX_MEMORY
	bool "Enable Sandbox Memory Controller driver"
	depends on SANDBOX && MEMORY
	help
	  This is a driver model based Memory Controller driver for sandbox.
	  Currently it is a stub only, as there are no usable uclass methods
	  yet.

config STM32_FMC2_EBI
	bool "Support for FMC2 External Bus Interface on STM32MP SoCs"
	depends on ARCH_STM32MP
	help
	  Select this option to enable the STM32 FMC2 External Bus Interface
	  controller. This driver configures the transactions with external
	  devices (like SRAM, ethernet adapters, FPGAs, LCD displays, ...) on
	  SOCs containing the FMC2 External Bus Interface.

config STM32_OMM
	bool "STM32 Octo Memory Manager"
	depends on ARCH_STM32MP
	help
	  This driver manages the muxing between the 2 OSPI busses and
	  the 2 output ports. There are 4 possible muxing configurations:
	  - direct mode (no multiplexing): OSPI1 output is on port 1 and OSPI2
	       output is on port 2
	  - OSPI1 and OSPI2 are multiplexed over the same output port 1
	  - swapped mode (no multiplexing), OSPI1 output is on port 2,
	       OSPI2 output is on port 1
	  - OSPI1 and OSPI2 are multiplexed over the same output port 2
	  It also manages :
	    - the split of the memory area shared between the 2 OSPI instances.
	    - chip select selection override.
	    - the time between 2 transactions in multiplexed mode.

config TI_AEMIF
	tristate "Texas Instruments AEMIF driver"
	depends on ARCH_KEYSTONE || ARCH_DAVINCI
	help
	  This driver is for the AEMIF module available in Texas Instruments
	  SoCs. AEMIF stands for Asynchronous External Memory Interface and
	  is intended to provide a glue-less interface to a variety of
	  asynchronuous memory devices like ASRAM, NOR and NAND memory. A total
	  of 256M bytes of any of these memories can be accessed at a given
	  time via four chip selects with 64M byte access per chip select.

config TI_GPMC
	bool "Texas Instruments GPMC driver"
	depends on ARCH_OMAP2PLUS || ARCH_KEYSTONE || ARCH_K3
	depends on MEMORY && CLK && OF_CONTROL
	help
	  This driver is for the General Purpose Memory Controller (GPMC)
          present on Texas Instruments SoCs (e.g. OMAP2+). GPMC allows
          interfacing to a variety of asynchronous as well as synchronous
          memory drives like NOR, NAND, OneNAND, SRAM.

if TI_GPMC
config TI_GPMC_DEBUG
	bool "Debug Texas Instruments GPMC timings"
	help
	  Enable this to print GPMC timings before and after the GPMC registers
	  are programmed. This should not be left enabled on production systems.
