menu "MTD Support" config MTD_PARTITIONS bool config MTD bool "Enable MTD layer" help Enable the MTD stack, necessary to interact with NAND, NOR, SPI-NOR, SPI-NAND, OneNAND, etc. config DM_MTD bool "Enable Driver Model for MTD drivers" depends on DM help Enable driver model for Memory Technology Devices (MTD), such as flash, RAM and similar chips, often used for solid state file systems on embedded devices. config MTD_NOR_FLASH bool "Enable parallel NOR flash support" help Enable support for parallel NOR flash. config SYS_MTDPARTS_RUNTIME bool "Allow MTDPARTS to be configured at runtime" depends on MTD help This option allows to call the function board_mtdparts_default to dynamically build the variables mtdids and mtdparts at runtime. config FLASH_CFI_DRIVER bool "Enable CFI Flash driver" help The Common Flash Interface specification was developed by Intel, AMD and other flash manufactures. It provides a universal method for probing the capabilities of flash devices. If you wish to support any device that is CFI-compliant, you need to enable this option. Visit for more information on CFI. config CFI_FLASH bool "Enable Driver Model for CFI Flash driver" depends on DM_MTD select FLASH_CFI_DRIVER help The Common Flash Interface specification was developed by Intel, AMD and other flash manufactures. It provides a universal method for probing the capabilities of flash devices. If you wish to support any device that is CFI-compliant, you need to enable this option. Visit for more information on CFI. config SYS_FLASH_USE_BUFFER_WRITE bool "Enable buffered writes to flash" depends on FLASH_CFI_DRIVER help Use buffered writes to flash. config FLASH_CFI_MTD bool "Enable CFI MTD driver" depends on FLASH_CFI_DRIVER help This option enables the building of the cfi_mtd driver in the drivers directory. The driver exports CFI flash to the MTD layer. config SYS_FLASH_PROTECTION bool "Use hardware flash protection" depends on FLASH_CFI_DRIVER help If defined, hardware flash sectors protection is used instead of U-Boot software protection. config SYS_FLASH_CFI bool "Define extra elements in CFI for flash geometry" depends on FLASH_CFI_DRIVER help Define if the flash driver uses extra elements in the common flash structure for storing flash geometry. config ALTERA_QSPI bool "Altera Generic Quad SPI Controller" depends on DM_MTD help This enables access to Altera EPCQ/EPCS flash chips using the Altera Generic Quad SPI Controller. The controller converts SPI NOR flash to parallel flash interface. Please find details on the "Embedded Peripherals IP User Guide" of Altera. config FLASH_PIC32 bool "Microchip PIC32 Flash driver" depends on MACH_PIC32 && DM_MTD help This enables access to Microchip PIC32 internal non-CFI flash chips through PIC32 Non-Volatile-Memory Controller. config RENESAS_RPC_HF bool "Renesas RCar Gen3 RPC HyperFlash driver" depends on RCAR_GEN3 && DM_MTD help This enables access to HyperFlash memory through the Renesas RCar Gen3 RPC controller. config HBMC_AM654 bool "HyperBus controller driver for AM65x SoC" depends on SYSCON help This is the driver for HyperBus controller on TI's AM65x and other SoCs source "drivers/mtd/nand/Kconfig" config SYS_NAND_MAX_CHIPS int "NAND max chips" depends on MTD_RAW_NAND || CMD_ONENAND || TARGET_S5PC210_UNIVERSAL || \ SPL_OMAP3_ID_NAND default 1 help The maximum number of NAND chips per device to be supported. source "drivers/mtd/spi/Kconfig" source "drivers/mtd/ubi/Kconfig" endmenu
