Hi Manuel --

It should be possible. You'll need to load bootarm.efi somehow, then 
"bootefi" it, and in the UEFI boot loader, "boot net0:netbsd" IIRC.

This all depends on U-Boot's UEFI implementation exposing a 
EFI_SIMPLE_NETWORK_PROTOCOL interface for the corresponding ethernet 
device. The "dev" command in the UEFI boot loader will print any devices 
found.

Take care,
Jared
