Say Y here if you wish to use one of the serial ports as the
system console--the system console is the device which
receives all kernel messages and warnings and which allows
logins in single user mode.
Even if you say Y here, the currently visible framebuffer console

you can alter that using a kernel command line, for example
"console=ttyAM1".
