I received a note from bodhi bodhi <mibodhi at gmail.com> that he is
successfully using NFS v3 with modern U-Boot (since 2014).

Here are the details of the environment that he included...

bootcmd_nfs=setenv nfs_server "192.168.0.224"; setenv nfs_path
"/srv/nfs/hosts/tldDebian2"; setenv nfs_bootcmd "run nfs_set_bootargs;
run nfs_boot"; setenv nfs_ipconfig
"192.168.0.229:192.168.0.224:192.168.0.1:255.255.0.0:tldDebian2::off";
setenv nfs_set_bootargs "setenv bootargs console=ttyS0,115200
root=/dev/nfs nfsroot=$nfs_server:$nfs_path,v3 rootfstype=nfs rootwait
 ip=$nfs_ipconfig $mtdparts"; setenv nfs_load_uimage "nfs 0x800000
$nfs_server:$nfs_path/boot/uImage"; setenv nfs_load_uinitrd "nfs
0x1100000 $nfs_server:$nfs_path/boot/uInitrd"; setenv nfs_load_dtb
"nfs 0x1c00000 $nfs_server:$nfs_path/boot/dts/kirkwood-pogo_e02.dtb";
setenv nfs_bootm "bootm 0x800000 0x1100000 0x1c00000"; setenv nfs_boot
"run nfs_load_uimage; run nfs_load_uinitrd; run nfs_load_dtb; run
nfs_bootm"; echo "Booting NFS root…"; run nfs_bootcmd

Thanks, Bodhi.

Cheers,
