help
This enables support for accessing all type of NAND flash
devices. For further information see

Show informational strings about the vendor and nand flash type
during startup
config NAND_READ_OOB

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

help
Support for NAND flash using GPMC. GPMC is a common memory
interface found on Texas Instrument's OMAP platforms

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_VERIFY_WRITE
bool "Verify NAND page writes"
help
This adds an extra check when data is written to the flash. The
NAND flash device internally checks only bits transitioning
from 1 to 0. There is a rare possibility that even though the
device thinks the write was successful, a bit could have been
flipped accidentally due to device wear or something else.
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_MUSEUM_IDS
bool "Enable chip ids for obsolete ancient NAND devices"
depends on MTD_NAND
default n
help
Enable this option only when your board has first generation
NAND chips (page size 256 byte, erase size 4-8KiB). The IDs
of these chips were reused by later, larger chips.
config MTD_NAND_IDS
tristate
config MTD_NAND_NOMADIK
tristate "ST Nomadik 8815 NAND support"

help
Driver for the NAND flash controller on the Nomadik, with ECC.
