Linux 2.6 8xx kernel booting vs watchdog

[Povolotsky, Alexander]

Hi,

I wonder if someone could help me with answering couple of my questions:

How watchdog resetting is handled for PPC 
in Linux 2.6 on the kernel level ?
Does one need to add code for it or is it supported "off the shelf" ?

Is "early printk" supported for PPC on 2.6 ?
If yes - how and where it could be enabled?

Thanks,
Alex
