In linux kernel since version 2.6.20 (release Date: 2007-02-04)
Say Y here if you wish to use an AMBA PrimeCell UART 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
(/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=ttyAMA0". (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.)
