mtd: nand: DaVinci: Add 4-bit ECC support for large page NAND chips
This patch adds 4-bit ECC support for large page NAND chips using the new
ECC mode NAND_ECC_HW_OOB_FIRST. The platform data from board-dm355-evm
has been adjusted to use this mode.
The patches have been verified on DM355 device with 2KiB-page Micron
devices using mtd-tests and JFFS2. Error correction up to 4 bits has
also been verified using nandwrite/nanddump utilities.
