|
|
original ECC values for these old Merakis are sadly not
|
|
provided by the vendor. It looks like Meraki just stuck
|
|
with what Broadcom's SDK was doing... which left this
|
|
up to the proprietary nand driver.
|
|
|
|
Note: The invalid setting was and is handled by brcmnand. It
|
|
falls back to "bch" in brcmnand_setup_dev() when ecc.algo is
|
|
set to NAND_ECC_ALGO_UNKNOWN (since "hw" is not in the list
|
|
above).
|
|
|
|
A correct nand-ecc-algo = "bch"; is already specified in the
|
|
included "bcm5301x-nand-cs0-bch8.dtsi". So this line can be
|
|
dropped.
