CONFIG_MTD_NAND_VERIFY_WRITE with Software ECC

[David Peverley]

Hi Ricard,

Thats a good analysis ; I've dug around as a result and found an
interesting tech note from Micron at :
    http://download.micron.com/pdf/technotes/nand/tn2917.pdf

They classify NAND failures into various types ; Permanent Failures
and Temporary Failures, with the temporary failures being split into
"Program Disturb", "Read disturb", "Over-programming" and "Data loss"
- I won't paraphrase further here as the Micron document describes it
better than I ever could! :-)
