8136508cd6 [MTD] [NAND] at91_nand: use at91_nand_{en,dis}able consistently.
Use at91_nand_enable(), at91_nand_disable() to manipulate enable_pin.
No functional changes.

2314488e81 [MTD] [NAND] at91_nand: control NCE signal
This driver did not control NCE signal during normal operations (only
enable NCE on probing and disable NCE on removing).  This patch make
NCE signal inactive on idle state.

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.

1ff184225b [MTD] [NAND] fix platform driver hotplug/coldplug
Since 43cc71eed1, the platform modalias is
prefixed with "platform:".  Add MODULE_ALIAS() to the hotpluggable MTD NAND
platform drivers, to re-enable auto loading.

NOTE: at91_nand for some reason disallows modular builds.  I'm assuming that's
just an oversight that will be fixed.

842b1a105c [MTD] [NAND] at91_nand: Make mtdparts option can override board info
Call parse_mtd_partitions before checking board's partition_info, so
that "mtdparts=" option can override board's default setting.

This patch allows you to specify at91_nand partitions on the
kernel command line using the mtdparts variable, if
CONFIG_MTD_CMDLINE_PARTS is set.

dd11b8cdf0 [MTD] NAND: Support for 16-bit bus-width on AT91.
Add support for 16-bit NAND bus-width for the AT91 NAND driver.

The 16-bit NAND is found on the Atmel AT91SAM9260-EK and AT91SAM9261-EK
boards.

Orignal Patch from Patrice Vilchez

42cb1403af [MTD] NAND: AT91 NAND driver
This version only differs from version posted by Savin Zlobec (20 Jun
2006) in that the AT91RM9200-specific chip-select / bus setup code has
been moved from the at91_nand.c driver into the processor-specific file.
