menuconfig NAND
bool "NAND support"
select MTD_NAND_IDS
help
This enables support for accessing all type of NAND flash
devices. For further information see
<http://www.linux-mtd.infradead.org/doc/nand.html>.
if NAND
config NAND_ECC_SOFT
bool
default y
prompt "Support software ecc"
config NAND_ECC_BCH
select BCH
bool
prompt "Support software BCH ecc"
config NAND_ECC_HW
bool
default y
prompt "Support hardware ecc"
config NAND_ECC_HW_OOB_FIRST
bool
prompt "Support hardware ecc (oob first)"
config NAND_ECC_HW_SYNDROME
bool
default y
prompt "Support syndrome hardware ecc controllers"
config NAND_ECC_HW_NONE
bool
default y
prompt "Support skipping ecc support"
config NAND_INFO
bool
default y
prompt "Nand vendor/size information"
help
Show informational strings about the vendor and nand flash type
during startup
config NAND_READ_OOB
bool
config NAND_BBT
bool
select NAND_READ_OOB
default y
prompt "support bad block tables"
help
Say y here to include support for bad block tables. This speeds
up the process of checking for bad blocks
config NAND_ALLOW_ERASE_BAD
bool
depends on MTD_WRITE
prompt "Add device parameter to allow erasing bad blocks"
help
This adds a 'erasebad' device parameter to nand devices. When set
to '1' it will be allowed to erase bad blocks. This is a potientially
dangerous operation, so if unsure say no to this option.
config NAND_IMX
bool
prompt "i.MX NAND driver"
depends on ARCH_IMX
config NAND_MXS
bool
select NAND_BBT
select STMP_DEVICE
prompt "i.MX23/28/6 NAND driver"
depends on MXS_APBH_DMA
config NAND_OMAP_GPMC
tristate "NAND Flash Support for GPMC based OMAP platforms"
depends on OMAP_GPMC
help
Support for NAND flash using GPMC. GPMC is a common memory
interface found on Texas Instrument's OMAP platforms
config MTD_NAND_OMAP_ELM
bool "Support for ELM (Error Location Module) on OMAP platforms"
depends on NAND_OMAP_GPMC || COMPILE_TEST
help
This config enables the ELM hardware engine, which can be used to
locate and correct errors when using BCH ECC scheme. This offloads
the cpu from doing ECC error searching and correction. However some
legacy OMAP families like OMAP2xxx, OMAP3xxx do not have ELM engine
so this is optional for them.
config NAND_ORION
bool
prompt "Marvell Orion NAND driver"
depends on ARM && (ARCH_KIRKWOOD || COMPILE_TEST)
help
Support for the Orion NAND controller, present in Kirkwood SoCs.
config NAND_MRVL_NFC
bool
prompt "Marvell PXA3xx NAND driver"
depends on ARCH_ARMADA_370 || ARCH_ARMADA_XP || ARCH_PXA3XX || COMPILE_TEST
help
Support for the PXA3xx NAND controller, present in Armada 370/XP and
PXA3xx SoCs.
config NAND_ATMEL
bool
prompt "Atmel (AT91SAM9xxx) NAND driver"
depends on ARCH_AT91
config NAND_ATMEL_PMECC
bool
prompt "PMECC support"
depends on NAND_ATMEL || COMPILE_TEST
select NAND_ECC_HW
help
Support for PMECC present on the SoC sam9x5 and sam9n12
config NAND_S3C24XX
bool
prompt "Samsung S3C24XX NAND driver"
depends on ARCH_S3C24xx
help
Add support for processor's NAND device controller.
config MTD_NAND_ECC_SMC
bool "NAND ECC Smart Media byte order"
default n
help
Software ECC according to the Smart Media Specification.
The original Linux implementation had byte 0 and 1 swapped.
config MTD_NAND_IDS
tristate
config MTD_NAND_NOMADIK
tristate "ST Nomadik 8815 NAND support"
depends on ARCH_NOMADIK
help
Driver for the NAND flash controller on the Nomadik, with ECC.
config MTD_NAND_DENALI
tristate "Support Denali NAND controller"
depends on HAS_DMA
help
Enable support for the Denali NAND controller. This should be
combined with either the PCI or platform drivers to provide device
registration.
config MTD_NAND_DENALI_DT
tristate "Support Denali NAND controller as a DT device"
depends on HAVE_CLK && MTD_NAND_DENALI
help
Enable the driver for NAND flash on platforms using a Denali NAND
controller as a DT device.
if MTD_NAND_DENALI
config MTD_NAND_DENALI_TIMING_MODE
int "Overrides default ONFI timing mode."
default -1
range -1 5
help
-1 indicates use default timings
