You have to add a "#define DEBUG" to the file you want to have the debug
messages from. Add this *above* the includes, just like in the kernel.

Something not mentioned in the wiki is that before the first console is
initialized barebox will print the messages into a ring buffer which it
will dump when the first console is initialized.
