I need to use that info in a script, that's why these env vars.
Ok. Honestly, it doesn't feel quite right to me.
I haven't played with U-Boot's shell too much but is there no way to
assign variables from command outputs? For example, can we do something
like `foo=$(cat a.txt)`? If that is possible, maybe add some new
subcommands to "sf" that return this information?
There is not.
IMO the current solution (exporting to environment variables in an ad-hoc
manner) is rather ugly, but fixing it is difficult :)
