Does UBI support MLC nand flash?

[Kyungmin Park]

Hi,

Refer to previous mail [1,2] related with terminology.

We have to check the flash type & flags such as MTD_OOB_WRITEABLE in mtd-utils too. Or use the mtd_ops to write main and oob
simultaneously if the detected chip is MLC.

Thank you,
Kyungmin Park

Sir,
     I don't know what is NOP, POP stand for? can you explain that?

     I notice mtd-utils "nandwrite.c" does write each page's oob area
twice, write oob(filesystem area) once, and then call "pwrite" to
write pagedata including oob (ecc part). I don't think that will work
right on MLC nand.
