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.

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.

bool "OneNAND 2X program support"
|
|
help
|
|
The 2X Program is an extension of Program Operation.
|
|
Since the device is equipped with two DataRAMs, and two-plane NAND
|
|
Flash memory array, these two component enables simultaneous program
|
|
of 4KiB. Plane1 has only even blocks such as block0, block2, block4
|
|
while Plane2 has only odd blocks such as block1, block3, block5.
|
|
So MTD regards it as 4KiB page size and 256KiB block size
|
|
|
|
Now the following chips support it. (KFXXX16Q2M)
|
|
Demux: KFG2G16Q2M, KFH4G16Q2M, KFW8G16Q2M,
|
|
Mux: KFM2G16Q2M, KFN4G16Q2M,
