whenever you updated the kernel or romfs,

you have to run "make" and "make linux image" again.

If you are using the MMU and you've generated a *.dts file to be linked then I'd bet that your sopc2dts has some entries that need to be tweeked. If there are unknown entries then you need to fix those first.
