In 1.1.4 there's a bunch of code in cmd_nand.c under #ifdef MTD_NAND_ECC (e.g., the
nand_correct_data() routine) which assumes 3 ECC bytes for each 256
byte block, and 6 bytes of ECC stored overall per 512 byte block. The
Samsung uses a scheme with 3 bytes per 512 byte block, leading me to
believe the current code is specific to some other chip.
