Older-style on-NAND data format has a "pageStatus" byte to record
|
|
|
|
|
chunk/page state. This byte is zeroed when the page is discarded.
|
|
|
|
|
Choose this option if you have existing on-NAND data in this format
|
|
|
|
|
that you need to continue to support. New data written also uses the
|
|
|
|
|
older-style format.
|
|
|
|
|
Note: Use of this option generally requires that MTD's oob layout be
|
|
|
|
|
adjusted to use the older-style format. See notes on tags formats and
