You bet:
- you force everybody to use early_printk (you only want it for
  debugging).
- you configure early_printk for everybody (never have to configure
  it).

You can't have the cake and eat it :(

Why do you ever will want not to use early_printk?

when you are using a console that is not the prom console (why do you
want to do that on MIPS is a misterios to me), but for other
archs/machines it make sense:

think on a machine that you now it boots to use a network console.

Later, Juan.
