Did you really test this on a mxs based board ?
If yes with which CPU and which NAND flash ?

At least one parameter (-s 512) is not synchronous with the log you
provide in the comment.

Moreover these settings are CPU and NAND flash dependent so I don't
think they belong to mxs-base.inc but to each board file according to
the flash which is populated.

Best regards,
Eric
