No. This is a shell script, so the shell will  substitute  the  first
argiument to the script here.

Just call it and pass the IP address (or host name, assuming  DNS  is
working) as first parameter.

Yes (or host name, assuming DNS is working)

Because ^C is used by U-Boot, too, and we need a (simple) way to pass
it through while still being able to terminate the script.

Because ^C is passed through to the U-Boot console.

This is perfectly reasonable - pressing ^C at the U-Boot console does
what is reasonablke: terminating the running U-Boot command  (instead
of throwing you out of the remote session).
