For BRCMNAND with 1-bit BCH ECC (BCH-1) such as used on the D-Link DIR-885L and DIR-890L routers, we need to explicitly select the ECC like this in the device tree:
nand-ecc-algo = "bch"; nand-ecc-strength = <1>; nand-ecc-step-size = <512>;
This is handled by the Linux kernel but U-Boot core does not respect this. Fix it up by parsing the algorithm and preserve the behaviour using this property to select software BCH as far as possible.
