[U-Boot] askenv with timeout?

Hi everyone,

Recently I got the need to read some environment variable from stdin, as user input. So, I discovered the 'askenv' command. One additional requirement I have is avoiding any blocking behavior, which would be possible if askenv supported the timeout concept. However, it doesn't seem to be the case in the 'do_env_ask' function. Here follow some questions:

- Will there be a timeout option for askenv in future? - What is the closest alternative right now (I believe some 'echo' statements combined with 'bootdelay')?

Thanks for your time.

Best regards, Eugeniu.
