This controller can be used to support both SLC and MLC NAND Flash devices. It supports to generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector of data. To use this driver, the user needs to pass in the correction capability and the sector size. This driver has been tested on AT91SAM9X5-EK and AT91SAM9N12-EK with JFFS2, YAFFS2, UBIFS and mtd-utils.

OK, I can spit to more patches.
Besides, it does not compile for me: ERROR: "of_flat_dt_is_compatible" [drivers/mtd/nand/atmel_nand.ko] undefined! ERROR: "of_get_flat_dt_root" [drivers/mtd/nand/atmel_nand.ko] undefined! make: *** [__modpost] Error 1
This function will depend on CONFIG_OF_FLATTREE and CONFIG_OF_EARLY_FLATTREE.
Would it be possible that CONFIG_OF is defined, but above two config options are not defined? Can I see you .config file go get more details?
