The code generating both errors is in the nand_do_read_ops function in nand_base.c:

   if (mtd->ecc_stats.failed - stats.failed)

   return  mtd->ecc_stats.corrected - stats.corrected ? -EUCLEAN : 0;

}

I understand that the -EUCLEAN error indicates a correctable ECC error. What does the -EBADMSG error indicate?

An uncorrectable ECC error (or other failure).

This condition doesn't seem to bother the linux driver, but u-boot doesn't like it at all!

Check whether the ECC layout and code is the same for this driver in both U-Boot and Linux.
