st_smi: Add support for SPEAr SMI driver

2012-07-07T12:07:38+00:00

SMI is the serial memory interface controller provided by ST.

Earlier, a driver exists in the u-boot source code for the SMI IP. However, it
was specific to spear platforms. This commit converts the same driver to a more
generic driver. As a result, the driver files are renamed to st_smi.c and
st_smi.h and moved into drivers/mtd folder for reusability by other platforms
using smi controller peripheral.

mtd/NAND: Add FSMC driver support

2012-07-07T12:07:38+00:00

Flexible static memory controller is a peripheral provided by ST,
which controls the access to NAND chips along with many other
memory device chips eg NOR, SRAM.

This patch adds the driver support for FSMC controller interfacing
with NAND memory.

linux/compat.h: rename from linux/mtd/compat.h

This lets us use it in more places than just mtd code.

onenand: Replace ONENAND_IS_MLC() with ONENAND_HAS_4KB()

2012-04-04T15:08:40+00:00

This replacement causes 4KB page size devices to work properly with u-boot.

The old ONENAND_IS_MLC() behavior has been preserved by explicit
setting of ONENAND_HAS_4KB_PAGE for those devices.

This change makes the onenand_base.c file more resembling the respective
kernel sources.

onenand:samsung Target dependent OneNAND chip probe function

2012-04-04T14:27:34+00:00

Separate callback for probing OneNAND memory chip.
If no special function is defined, default implementation will be used.

This approach gives more flexibility for OneNAND device probing.

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.
