By enabling this option you take advantage of dma feature available

Select this option if you would like to use omap serial port as
console.
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=ttyOx". (Try "man bootparam" or see the documentation of
your boot loader about how to pass options to the kernel at
boot time.)
