What I'd really like to have is to be able to, at compile time, associate a debug console with a PBL entry point that would also work prior to relocation. That debug console should be inherited into barebox proper to be used until a console driver was initialized. We are not there yet though and I still didn't figure some stuff out. So I'd prefer postponing this more generic until a second boards needs it.
