6 tristate "OneNAND Device Support"
9 This enables support for accessing all type of OneNAND flash
10 devices. For further information see
11 <http://www.samsung.com/Products/Semiconductor/OneNAND/index.htm>
15 config MTD_ONENAND_VERIFY_WRITE
16 bool "Verify OneNAND page writes"
18 This adds an extra check when data is written to the flash. The
19 OneNAND flash device internally checks only bits transitioning
20 from 1 to 0. There is a rare possibility that even though the
21 device thinks the write was successful, a bit could have been
22 flipped accidentally due to device wear or something else.
24 config MTD_ONENAND_GENERIC
25 tristate "OneNAND Flash device via platform device driver"
28 Support for OneNAND flash via platform device driver.
30 config MTD_ONENAND_OTP
31 bool "OneNAND OTP Support"
33 One Block of the NAND Flash Array memory is reserved as
34 a One-Time Programmable Block memory area.
35 Also, 1st Block of NAND Flash Array can be used as OTP.
37 The OTP block can be read, programmed and locked using the same
38 operations as any other NAND Flash Array memory block.
39 OTP block cannot be erased.
41 OTP block is fully-guaranteed to be a valid block.
