The most common problem with serial devices is not enabling
CYGPKG_IO_SERIAL_DEVICES. Obviously you also have to include the
CYGPKG_IO_SERIAL package too.
Note that AT91 serial devices cannot be shared between diagnostics and
serial drivers. So if you want to continue using diagnostics on a
particular UART, you need to disable it for the drivers.
