9 tristate "OneNAND Device Support"
12 This enables support for accessing all type of OneNAND flash
13 devices. For further information see

16 config MTD_ONENAND_VERIFY_WRITE
17 bool "Verify OneNAND page writes"
18 depends on MTD_ONENAND
20 This adds an extra check when data is written to the flash. The
21 OneNAND flash device internally checks only bits transitioning
22 from 1 to 0. There is a rare possibility that even though the
23 device thinks the write was successful, a bit could have been
24 flipped accidentally due to device wear or something else.
26 config MTD_ONENAND_GENERIC
27 tristate "OneNAND Flash device via platform device driver"
28 depends on MTD_ONENAND && ARM
30 Support for OneNAND flash via platform device driver.

33 bool "OneNAND OTP Support"
34 depends on MTD_ONENAND
36 One Block of the NAND Flash Array memory is reserved as
37 a One-Time Programmable Block memory area.
38 Also, 1st Block of NAND Flash Array can be used as OTP.
40 The OTP block can be read, programmed and locked using the same
41 operations as any other NAND Flash Array memory block.
42 OTP block cannot be erased.
44 OTP block is fully-guaranteed to be a valid block.
