+
+ Older-style on-NAND data format has a "pageStatus" byte to record
+ chunk/page state. This byte is zero when the page is discarded.
+ Choose this option if you have existing on-NAND data using 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 MTD versions
+ in yaffs_mtdif1.c.
+
+ If unsure, say N.
