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

[Simon Glass]

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)

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.
