18 provided by the vendor. It looks like Meraki just stuck
19 with what Broadcom's SDK was doing... which left this
20 up to the proprietary nand driver.
22 Note: The invalid setting was and is handled by brcmnand. It
23 falls back to "bch" in brcmnand_setup_dev() when ecc.algo is
24 set to NAND_ECC_ALGO_UNKNOWN (since "hw" is not in the list
27 A correct nand-ecc-algo = "bch"; is already specified in the
28 included "bcm5301x-nand-cs0-bch8.dtsi". So this line can be
