    IFAIK, the feature of NAND hardware ECC is in support in kernel.
    But the problem is, the dfu-util did not program the ECC field. 
    You will see the ECC error message flooding during booting once ECC 
feature is enabled.

    If you want to enable ECC support, plan A) is to use mtd utility to 
flash rootfs.
    The plan B) is to add feature of programing ECC field when DFU-ing 
in the uboot.
