Hi all,

this should be interesting for the embedded and evaluation board
fraction on this list.  I'd appreciate if someone of them'd check
out and report,

>                       consolemap, selection, keyboard and defkeymap
> CONFIG_VT_CONSOLE     for directing printk to the VT device
> CONFIG_VT_SERIAL      for directing printk to the standard serial device
> 
> Both CONFIG_VT_CONSOLE and CONFIG_VT_SERIAL can be used together in
> which case the output goes to both. To support this, there is a new
> console device list with entries for this output. The list also has
> entries for waiting a key press and for determining what device really

> the head of the list.

> The rest of the change is to move some code from tty_io.c to other
