We need to calculate the ecc parameters in a way that are the same in uboot and spl. The parameters are connected to the onfi computation. We need to assign all the value of chip in order to have same ecc strength parameters before calling mxs_nand_set_geometry that calculate the ecc layout /* use the legacy bch setting by default */ if ((!nand_info->use_minimum_ecc && mtd->oobsize < 1024) || !(chip->ecc_strength_ds > 0 && chip->ecc_step_ds > 0)) { dev_dbg(mtd->dev, "use legacy bch geometry\n"); err = mxs_nand_legacy_calc_ecc_layout(geo, mtd); if (!err) return 0; } Signed-off-by: Michael Trimarchi <michael@amarulasolutions.com> --- drivers/mtd/nand/raw/mxs_nand_spl.c | 6 ++++++ 1 file changed, 6 insertions(+)
