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.").

Revert "nand: make 1-bit software ECC configurable"

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

This reverts commit 4fee6c2f295f932b8febdc7ce8731ba045695fa5.

It breaks boards that currently rely on soft-ecc, as pointed out here:
http://patchwork.ozlabs.org/patch/140872/

The reverted patch should be resubmitted with documentation, and with the
CONFIG_MTD_ECC_SOFT selected from every board that needs it.  We could
start by looking at what NAND driver the board selects, and whether
that driver ever asks for soft ECC.

nand: make 1-bit software ECC configurable

2012-01-26T22:09:02+00:00

The software ECC algorithm is not necessary when hardware ECC
is available and can be left out for a smaller image size.
Enable with CONFIG_MTD_ECC_SOFT.

nand: Merge BCH code from Linux nand driver

2012-01-26T22:09:02+00:00

[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 common functions to linux/mtd/nand.h

2011-12-06T22:59:31+00:00

Functions often used in SPL are now part of linux/mtd/nand.h.
Static modifiers are removed from these functions in
drivers/mtd/nand/nand_base.c.

Convert ISO-8859 files to UTF-8

2011-08-04T21:34:02+00:00

There was a mix of UTF-8 and ISO-8859 files in the U-Boot source
tree, which could cause issues with the patchwork review system.
This commit converts all ISO-8859 files to UTF-8.

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.
