Without /dev/, i.e. "console=hvc0".  But, yes, that should be it.  Works
for me.

Doesn't compile due to setup_early_printk() being gone.

I also think we don't need early_printk in xen any more.  The hvc
console supports a two-step setup.  One can be done very early at boot
(hvc_instantiate) and one later on, once everything (memory, irqs) is up
and running, during normal device initialization (hvc_alloc).

I'm still playing with it a bit and browse through the console code.
Right now early hvc initialization happens in console_init, I'll try to
do it earlier at boot.

cheers,
