To be precise the statically linked kernel + dtb can be loaded by u-boot 
over tftp (and nfs). The kernel modules are typically part of the rootfs 
so they would be exported by nfs in our scenario.

I usually use symbolic links in my tftp export as well as which nfs 
rootfs I export so I don't need to change the u-boot environment to boot 
from something different. Like this it's just a matter of copying things 
around on your PC and adjusting the symlinks.
