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. > Mostly the existing code can be re-used and I have tried to avoid too > much refactoring or cleaning up. :) > The feature is activated by the CONFIG_CMD_TFTPPUT option. > > This has been very lightly tested on a Seaboard with a USB network > adaptor. I don't think it handles block number overflow.

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.
