In linux kernel since version 2.6.24 (release Date: 2008-01-24)  
Support for the asynchronous serial interface (DUART) included in
the BCM1250 and derived System-On-a-Chip (SOC) devices. Note that
the letter D in DUART stands for "dual", which is how the device
is implemented. Depending on the SOC configuration there may be
one or more DUARTs available of which all are handled.

If unsure, say Y. To compile this driver as a module, choose M here:
the module will be called sb1250-duart.
