While that is often a safe assumption to -make, let's make it explicit, since we have that information. - -Signed-off-by: Brian Norris <computersforpeace@gmail.com> -Acked-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> -Tested-by: Daniel Mack <zonque@gmail.com> ---- - drivers/mtd/nand/pxa3xx_nand.c | 15 ++++++++++++--- - 1 file changed, 12 insertions(+), 3 deletions(-) - ---- a/drivers/mtd/nand/pxa3xx_nand.c -+++ b/drivers/mtd/nand/pxa3xx_nand.c -@@ -1364,9 +1364,13 @@ static int pxa_ecc_init(struct pxa3xx_na - - static int armada370_ecc_init(struct pxa3xx_nand_info *info, - struct nand_ecc_ctrl *ecc, -- int strength, int page_size) -+ int strength, int ecc_stepsize, int page_size) - { -- if (strength == 4 && page_size == 4096) { -+ /* -+ * Required ECC: 4-bit correction per 512 bytes -+ * Select: 16-bit correction per 2048 bytes -+ */ -+ if (strength == 4 && ecc_stepsize == 512 && page_size == 4096) { - info->ecc_bch = 1; - info->chunk_size = 2048; - info->spare_size = 32; -@@ -1377,7 +1381,11 @@ static int armada370_ecc_init(struct pxa - ecc->strength = 16; - return 1; - -- } else if (strength == 8 && page_size == 4096) { -+ /* -+ * Required ECC: 8-bit correction per 512 bytes -+ * Select: 16-bit correction per 1024 bytes -+ */ -+ } else if (strength == 8 && ecc_stepsize == 512 && page_size == 4096) { - info->ecc_bch = 1; - info->chunk_size = 1024; - info->spare_size = 0; -@@ -1485,6 +1493,7 @@ KEEP_CONFIG: - if (info->variant == PXA3XX_NAND_VARIANT_ARMADA370) - ret = armada370_ecc_init(info, &chip->ecc, - chip->ecc_strength_ds, -+ chip->ecc_step_ds, - mtd->writesize); - else - ret = pxa_ecc_init(info, &chip->ecc, |
