menu "MTD Support"
config MTD_PARTITIONS
bool
config MTD
bool "Enable MTD layer"
help
Enable the MTD stack, necessary to interract 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 <http://www.amd.com/products/nvd/overview/cfi.html>
for more information on CFI.
config CFI_FLASH
bool "Enable Driver Model for CFI Flash driver"
depends on DM_MTD

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
