No. So far U-Boot implements a TFTP client only. There is  no  server
fuctionality of any kind.

I don't understand this. How is this affected by U-Boot being  server
or client? You can do the same in both configurations. We have U-Boot
and  Linux  running  on systems with just a 128 kB EPROM (yes, a real
UV-erasable EPROM, you remember?).
