This patch adds software BCH ECC support to mtd, in order to handle recent NAND device ecc requirements (4 bits or more). It does so by adding a new ecc mode (NAND_ECC_SOFT_BCH) for use by board drivers, and a new Kconfig option to enable BCH support. It relies on the generic BCH library introduced in a previous patch. When a board driver uses mode NAND_ECC_SOFT_BCH, it should also set fields chip->ecc.size and chip->ecc.bytes to select BCH ecc data size and required error correction capability. See nand_bch_init() documentation for details. It has been tested on the following platforms using mtd-utils, UBI and UBIFS: x86 (with nandsim), arm926ejs.
