In linux kernel since version 2.6.20 (release Date: 2007-02-04)
If you have enabled the serial port on the Intel XScale PXA
CPU you can make it the console by answering Y to this option.
Even if you say Y here, the currently visible virtual console
(/dev/tty0) will still be used as the system console by default, but
you can alter that using a kernel command line option such as
"console=ttySA0". (Try "man bootparam" or see the documentation of
your boot loader (lilo or loadlin) about how to pass options to the
kernel at boot time.)
