Not sure what this (EINVAL on ECC init) means exactly, but it looks like it dislikes the kind of NAND chip used. This NAND chip is not providing JEDEC information so a lookup table compiled in the driver is used for determining the NAND chip parameters. Maybe there is invalid parameters in that table, or the NAND chip requires an ECC mode not yet supported by the driver.
