    mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver

    The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It
    silently masks off at least one flag that might be set by the driver
    (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly
    others.

    Really, as long as driver writers exercise a small amount of care with
    NAND_* options, this mask is not necessary at all; it was only here to
    prevent certain options from accidentally being set by the driver. But the
    original thought turns out to be a bad idea occasionally. Thus, kill it.

    Note, this patch fixes some major gpmi-nand breakage.

nand: Try to align the default buffers

2012-09-07T20:54:30+00:00

The NAND layer needs to use cache-aligned buffers by default. Towards this
goal. align the default buffers and their members according to the minimum
DMA alignment defined for the architecture.

nand: reinstate lazy bad block scanning

2012-02-28T20:03:39+00:00

commit 2a8e0fc8b3dc31a3c571e439fbf04b882c8986be ("nand: Merge changes
from Linux nand driver") accidentally reverted commit
13f0fd94e3cae6f8a0d9fba5d367e311edc8ebde ("NAND: Scan bad blocks
lazily.").

Reinstate the change, as amended by commit
ff49ea8977b56916edd5b1766d9939010e30b181 ("NAND: Mark the BBT as scanned
prior to calling scan_bbt.").

nand: Merge BCH code from Linux nand driver

[backport from linux commit 02f8c6aee8df3cdc935e9bdd4f2d020306035dbe]

This patch merges the BCH ECC algorithm from the 3.0 Linux kernel.
This enables U-Boot to support modern NAND flash chips that
require more than 1-bit of ECC in software.

NAND: add support for reading ONFI page table

2011-04-01T19:49:08+00:00

This patch adds support for reading an ONFI page parameter from a NAND
device supporting it. If this is the case, struct nand_chip onfi_version
member contains the supported ONFI version, 0 otherwise.

This allows NAND drivers past nand_scan_ident to set the best timings for the
NAND chip.
