Especially I find it interesting for backing up things like MTD and 
small disk files (not partitions, though). Most of my work currently is 
trying to bring mainline U-Boot support to existing boards with bad 
U-Boot implementations, and being able to backup things from U-Boot (as 
opposed to having to set up NFS root and Linux boot) would definitely be 
a plus.

What size does this limit transfers to?

Many U-Boot environments use 'tftp' as a shorthand to tftpboot. Did you 
verify that this is not broken by the introduction of 'tftpput'?

Also, I'd be happy to test this if a branch exists that already holds 
these commits.
