Cover letter [U-Boot] [PATCH 0/8] Add tftpput command for uploading files over network

The tftpboot command permits reading of files over a network interface using the Trivial FTP protocol. This patch series adds the ability to transfer files the other way.

Why is this useful?

- Uploading boot time data to a server
- Uploading profiling information
- Uploading large mounts of data for comparison / checking on a host (e.g. use tftpput and ghex2 instead of the 'md' command)

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.

What size does this limit transfers to?

Simon Glass (8):
Move simple_itoa to vsprintf
Add setenv_uint() and setenv_addr()
tftpput: Rename TFTP to TFTPGET
tftpput: move common code into separate functions
tftpput: support selecting get/put for tftp
tftpput: add save_addr and save_size global variables
tftpput: implement tftp logic
tftpput: add tftpput command

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.

Amicalement,
