The problem I have is not really how to put the kernel in NAND, but how to upgrade it. I don't really want to overwrite what I have, instead I want to load another image and have u-boot be able to pick up one or the other. This way, I can have two copies and in case the new version is bad, I can always have one to fall back on. This is why, I was thinking that either having a soft link to a file in a single partition nand or have three separate partitions (two of them for kernel, one for file system).
Why not simply using different names for both images, and switching the boot filename in U-Boot? Remember that U-Boot is scriptable, so this is a trivial thing to do.
