    mtd: flash drivers set ecc strength · 6a918bad
    Mike Dunn authored
    Flash device drivers initialize 'ecc_strength' in struct mtd_info, which is the
    maximum number of bit errors that can be corrected in one writesize region.
    
    Drivers using the nand interface intitialize 'strength' in struct nand_ecc_ctrl,
    which is the maximum number of bit errors that can be corrected in one ecc step.
    Nand infrastructure code translates this to 'ecc_strength'.
    
    Also for nand drivers, the nand infrastructure code sets ecc.strength for ecc
    modes NAND_ECC_SOFT, NAND_ECC_SOFT_BCH, and NAND_ECC_NONE.  It is set in the
    driver for all other modes.
