Dear Gianluca,

I send you my patch for s3c2410 ARM processor. This patch implements boot directly from nandflash. I haven't created new board in board directory but I have writed new config-file (smdk2410nand.h) that use smdk2410 board.
I have forwarded your patch to David Müller who is the maintainer for the SMDK2410 board; I cannot test it myself.
I tested with MAKEALL ARM9 my patch. I changed the frequency of internal clock of s3c2410 (for smdk2410 borad) because (only) in this way the Linux Mizi kernel can boot correctly. The patch is based on u-boot 0.4.8.
This is my first contribution to open source and I hope that it is useful to someone.
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
