Currently the wget command is hard wired to HTTP port 80. This is inconvenient, as it is extremely easy to start trivial HTTP server as an unprivileged user using e.g. python http module to serve the files, but such a server has to run on one of the higher ports: " $ python3 -m http.server -d $(pwd) 8080 " Make it possible to configure HTTP server port the same way it is possible to configure TFTP server port, using environment variable 'httpdstp' (similar to 'tftpdstp'). Retain port 80 as the default fallback port. This way, users can start their own trivial server and conveniently download whatever files they need into U-Boot.
