I have forwarded your patch to David Müller who is the maintainer for
the SMDK2410 board; I cannot test it myself.

It is definitely useful, but I have a couple of questions:
* Which problem are you trying to address which is not supported by
the existing NAND code?
* Is it necessary to implement this in a processor specific way?
* You add new configuration options like CONFIG_S3C2410_NAND_BOOT but
do not include any dosumentation. At least, please provide an
explantion of these options for the README fie. If you feel longer
explanations are needed create a new file doc/README.NAND-Boot or
so.
David, I've forwarded the patch to you. Can you please have a look at
the implementation details? Thanks.
Best regards,
Wolfgang Denk
