You nead a uImage. Just use the same kernel sources and do make uImage
instead of zImage.
Does anyone have an example for doing this? I am not
sure what address should I use to load the kernel into
RAM.
Load it to 0x8080. You can also try the patch below, which will give
you a better default environment, it shall be submitted to the list soon.
