└─>PXA serial port support (DEPRECATED)
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
If you have a machine based on an Intel XScale PXA2xx CPU you
can enable its onboard serial ports by enabling this option.

Unless you have a specific need, you should use SERIAL_8250_PXA
instead of this.
