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.

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.

Since 43cc71ee, 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.

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.

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.

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.
