menuconfig MTD_ONENAND
tristate "OneNAND Device Support"
depends on MTD
help
This enables support for accessing all type of OneNAND flash
devices. For further information see
<http://www.samsung.com/Products/Semiconductor/Flash/OneNAND_TM/index.htm>.
if MTD_ONENAND
config MTD_ONENAND_VERIFY_WRITE
bool "Verify OneNAND page writes"
help
This adds an extra check when data is written to the flash. The
OneNAND 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_ONENAND_GENERIC
tristate "OneNAND Flash device via platform device driver"
depends on ARM
help
Support for OneNAND flash via platform device driver.
config MTD_ONENAND_OTP
bool "OneNAND OTP Support"
help
One Block of the NAND Flash Array memory is reserved as
a One-Time Programmable Block memory area.
Also, 1st Block of NAND Flash Array can be used as OTP.
The OTP block can be read, programmed and locked using the same
operations as any other NAND Flash Array memory block.
OTP block cannot be erased.
OTP block is fully-guaranteed to be a valid block.
