Yeah, it sounds like a nice idea to use the same protocol for 
everything, but another way of looking at it is to use the protocol 
that's best-suited for the job. TFTP was designed to efficiently move 
large blocks of data in one direction. NFS was designed with very 
different and much more complicated goals. As you've seen, the U-boot 
implementation is very lean and that's the way it should be, since file 
systems play a very limited role in bootloaders. The overhead and 
maintenance of running a TFTP server is, well, trivial.
