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,

> This patch is to make the virtual terminal tty devices be a
> configuration option. This is of use to those wanting to run Linux on
> machines that have no video or keyboard hardware.
> The patch is needed by few groups porting Linux to MVME or other
> embedded systems. However, this is just about all I can do to it
> without your feedback.
> The patch defines three new CONFIG_ macros
> CONFIG_VT for inclusion of console, vt, vc_screen,
> 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
> to open for /dev/console, but these are used only from the device at
> the head of the list.
> The rest of the change is to move some code from tty_io.c to other
> files where it seems to fit better. This avoids some #ifdef CONFIG_VT
> / #endif.
