bootloader on s3c2410(boot from NAND)

I have a board of s3c2410, with a 64M nand flash(k9f1208uom-ycb0), two 32M sdram( hy57v561620ct-h).
I want to port uboot on this board, and now i get a uboot modified by someone,it can run to the command line like SMDK2410#. And i want to it autoboot the linux and rootfs.I have the linux kernel and rootfs.cramfs which run well on vivi.So i only make uimage with mkimage and then modify boot args in /include/configs/s3c2410.h. the code is as follow, but it can't boot and also the memory content in 0x32000000 is not the uimage. so i hope someone having experiences in the situation be nice to give some info or advices. thanks all
best
regards

it's the start info

All this makes little sense to me.

U-Boot has been ported to the SMDK2410 a long, long time ago, so there is no need for you to to it again and reinvent the wheel.

If you got a modified version of U-Boot you should

(1) also have gotten the full source code or at least a written offer

    how you can get the source code for free;

(2) contact those guys who performed the modifications

On this mailing list you will get help for the official version of U-Boot only (= built from the public CVS source tree).

How many Unix hacks does it take to change a light bulb?  Let's  see,
   can you use a shell script for that or does it need a C program?

i am sorry not to describe it clearly
i am porting on s3c2410, but i have not see s3c2410 directory in /board/, so there is someone make the directory refer to smdk2410. maybe i can change my question ashow can i port uboot on s3c2410(boot from nand) on the new version of u-boot-1.1.2?

I really cannot parse this. Sorry. You ust not expect any processor specific code in a board directory - only board specfic code should be there. Processor specific code is in the cpu/* direcotories only.

1) u-boot-1.1.2 is not a new version; it is very old, and you can more or less consider it as obsolete.

In any case you should NOT base any current work on such old code. Please use top-of-tree in CVS instead.

2) U-Boot includes support for the s3c2410 processor on the SMDK2410 evaluation board. If you have such a board, then no port is necessary. If you have different hardware, than youy do have to port U-Boot; see the README for details.
