Re: [U-Boot] lowlevel_init.s for ARM920t/S3C2410
Alternatively, I have seen some unofficial u-boot ports for s3c24x0 cpu's that do support u-boot booting from NAND flash but I don't have the source code for them.
Kevin, I think this[1] is the code you are talking about. I just give it a try and it works like a charm when booting from NAND flash. They have a nand_read.c under cpu/arm920t/s3c24xx, which its object file is included just under start.o in the linker script. They also have a slightly different start.S in which they determinate if we're booting from NAND or NOR flash.
cheers,

I hadn't seen that but, yes, it's similar to another I've seen.
It seems to be based on a version of u-boot from March 2008 but I guess it wouldn't be too difficult to add something similar into the latest u-boot.
