Yeah, of course.

And the u-boot script is explicitly configured to use it:

env set serverip 192.168.1.2
env set baudrate 115200
env set bootargs boot.nfsroot.server=${serverip} 
boot.nfsroot.path=<PATH> comconsole_speed=${baudrate}
tftpboot ${kernel_addr_r} loader.efi
bootefi ${kernel_addr_r} ${fdtcontroladdr}

It's not getting to NFS. tcpdump shows no nfs activity from the board's 
IP address. Only ARP, TFTP and some weird UDP ports, all before 
loader.efi starts.

A Raspberry Pi 3 boots fine with about the same setup (minus baudrate, 
plus fdt from file).

Also, just checked: the nfs command in U-Boot actually tries to 
connect, 'sunrpc' and 'cadlock2' show up on tcpdump.
Nothing shows up with loader.efi, and it terminates *instantly*.
It clearly cannot find the Ethernet device itself.

Could you please send me the loader.efi that works for you?
And which version of U-Boot you use it with.
