So do I but I'm working with a u-boot my customer has modified to add it 
as a board-specific command. When I tried to use it on a new board with 
the latest u-boot  I found it wasn't a standard u-boot command. It's 
almost identical to "tftpboot" except that if "autostart" is set to 
"yes" "tftpboot" automatically boots from the file after it's downloaded 
it but "tftp" doesn't. I use it to copy images across then manually 
program them into flash.
