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

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.

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.

MTD:NAND: ADD new ECC mode NAND_ECC_HW_OOB_FIRST

2009-08-26T20:37:03+00:00

This patch adds the new mode NAND_ECC_HW_OOB_FIRST in the nand code to
support 4-bit ECC on TI DaVinci devices with large page (up to 2K) NAND
chips.  This ECC mode is similar to NAND_ECC_HW, with the exception of
read_page API that first reads the OOB area, reads the data in chunks,
feeds the ECC from OOB area to the ECC hw engine and perform any
correction on the data as per the ECC status reported by the engine.
