The only point is we need that the controller checks the parameters
after the tail part, as the tail part scans the chip and sets its
options, as the SUBPAGE flag. We could add a pre_adjust() and

Hi Scott,
Davinci-specific #defines do not belong in nand_base.c[1]. The controller

one.

No, really not.

Hi Stefano,
Hi Ben,
Thanks for sharing this patch -- I have been using the -O 2048 (VID
header offset) option to prevent subpages here.
Yes, this works too, at least with Linux.

The NAND controller does not support subpage accessing. This is
not used at all for MLC NAND, but it is set for SLC NAND. UBI tries
to access to subpages, and because it fails, it starts torture tests
