d43fa14996 [MTD] [NAND] AT91 hardware ECC compile fix for at91sam9263 / at91sam9260
The sam926x docs allegedly don't list an "ECC_PARITY" field, and the 
header files in the upstream kernel don't have it either.

Masking with it was useless anyway, so just remove it.

77f5492c43 [MTD] [NAND] Hardware ECC controller on at91sam9263 / at91sam9260
This is a patch to use the hardware ECC controller of
the AT91SAM9260 and AT91SAM9263 for the AT91 nand.
On AT91 NAND, there's now a choice between ECC soft,
ECC hard or no ECC (for debug).

It has been tested on AT91SAM9263 with 8 bits large
and small page NAND.

ed8165c75e [MTD] [NAND] Verify probe by retrying to checking the results match
With modern systems using bus-hold instead of bus pull-up, it can
often lead to erroneous reporting of NAND devices where there are
none. Do a double probe to ensure that the result we got the first
time is repeatable, and if it is not then return that there is no
chip there.

93919d384d [MTD] [NAND] plat_nand: set mtd->name
This patch sets mtd->name to the platform bus ID in the plat_nand
driver, so that you can specify partitions readily with mtdparts=.

Currently it relies on nand_base filling in the name from the device,
which results in names like "NAND 256MiB 3,3V 8-bit", that you can't
use with cmdlineparts.

9ebed3e60f [MTD] [NAND] fsl_elbc_nand: fix mtd name
Currently fsl_elbc_nand doesn't initialize mtd->name, and this causes
nand_get_flash_type() to assign name that is equal to chip type, like
this:

   root@b1:~# cat /proc/mtd
   dev:    size   erasesize  name
   mtd0: 00800000 00010000 "fe000000.flash"
   mtd1: 02000000 00004000 "NAND 32MiB 3,3V 8-bit"

mtd0 is physmap_of flash (normal name), and mtd1 is fsl_elbc_nand.

Despite inconsistency, with mtd name like this specifying paritions
from the kernel command line becomes a torture (though, I didn't tried
and not sure if mtdparts= can handle spaces at all). Plus, this causes
real bugs when multiple fsl_elbc_nand chips registered.

With this patch applied fsl_elbc_nand chip will have proper name:

   root@b1:~# cat /proc/mtd
   dev:    size   erasesize  name
   mtd0: 00800000 00010000 "fe000000.flash"
   mtd1: 02000000 00004000 "e0600000.flash"

p.s. We can't use priv->dev->bus_id as in physmap_of, because
fsl_elbc_nand pretends to be a localbus controller, so its bus_id is
"address.localbus", which is incorrect and thus will also not work
for multiple chips.

fe69af002e [MTD] [NAND] support for pxa3xx
This is preliminary since:

1. It supports only _one_ chip select at the moment. As there is no
   existing platforms available using two chip selects of the NAND
   controller, it shall really not include code for supporting the
   2nd chip select for now, as such code cannot be verified.

2. It resorts to the default and simpliest memory based badblock
   table

3. Only limited types of nand flash are currently supported. Most
   PXA3xx processors come with on-chip NAND flash dies, so there
   isn't much flexibility for other types of NAND.

4. The NAND controller should be configured to detect the device's
   ID, thus making it difficult to use nand_scan_ident() to assist
   the detection process (though it's not impossible)

TODO: fix all the above limitations of cuz :-)

c27e9b80be [MTD] [NAND] fix possible Ooops in rfc_from4
I found this while I was looking how the rs_lib is working.  The rs_decoder is
initialized _after_ the nand core code read the BBT table and _after_ the
partition table has been added.  The driver has a private BBT description
which is in located in flash data so we Ooops if there is a bit flip _or_ if a
bit flips while reading the partition table.

This patch moves the initialization of the rs_lib before the first possible
access by nand core.

03680b1e00 [MTD] [NAND] S3C2410 correctly set nFCE over resume
Ensure the nFCE line is de-asserted over suspend and
then re-initialised when the system resumes. This is
to ensure that the NAND is kept in lowest power mode
over suspend (power settings are only specified for
nFCE inactive) as well as fixing the Simtec Osiris
which relies on nFCE being inactive.

eb68450715 [MTD] [NAND] Replace -1 with -EBADMSG in nand error correction code
Magic numerical values are just bad style.  Particularly so when
undocumented.

c32b8dcc45 [MTD] [NAND] treat any negative return value from correct() as an error
Treat any negative return value from a NAND driver's correct() function
as a failure, rather than just -1.
