676 * Set UBI min. I/O size (@ubi->min_io_size). We use @mtd->writebufsize
677 * for these purposes, not @mtd->writesize. At the moment this does not
678 * matter for NAND, because currently @mtd->writebufsize is equivalent to
679 * @mtd->writesize for all NANDs. However, some CFI NOR flashes may
680 * have @mtd->writebufsize which is multiple of @mtd->writesize.
681 *
682 * The reason we use @mtd->writebufsize for @ubi->min_io_size is that
683 * UBI and UBIFS recovery algorithms rely on the fact that if there was
684 * an unclean power cut, then we can find offset of the last corrupted
685 * node, align the offset to @ubi->min_io_size, read the rest of the
686 * eraseblock starting from this offset, and check whether there are
687 * only 0xFF bytes. If yes, then we are probably dealing with a
688 * corruption caused by a power cut, if not, then this is probably some
689 * severe corruption.
690 *
691 * Thus, we have to use the maximum write unit size of the flash, which
692 * is @mtd->writebufsize, because @mtd->writesize is the minimum write
693 * size, not the maximum.
