The raw NAND layer may want to use one or another ECC provider if the
user did not explicitly broadcasted his choice through the DT. Raw
NAND controllers can also want to force these values. In any case, the
NAND core must be able to know their preference and this works by
letting subsystems/drivers filling/changing the "defaults" ECC
