# # Memory devices # menu "Memory Controller drivers" 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 "Support for Atmel EBI" 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 TI_AEMIF tristate "Texas Instruments AEMIF driver" depends on ARCH_KEYSTONE 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. endif endmenu
