Besides what Baruch already pointed out you can of course create your
own command. Maybe you don't want to have this command in your
production bootloader, then you could also build a barebox for
development only and start this as a second stage loader (tftp
barebox.bin /dev/ram0; go /dev/ram0).

Another possibility would be to use modules. barebox supports modules
similar to the kernel. When you build your own command as a module
you can do a 'tftp mycommand.ko; insmod mycommand.ko' and can use
your command then. Anyway, this feature is a bit experimental and
I can't really recommend this unless you know exactly what you
are doing.
