ms_serial driver

Hi,

I am porting the mainstoneii serial driver to my platform (wince5, pxa270
based on mainstoneii) for FFUART.
I enable the interrupt as

GetRegister()->Write_IER(bIER | BUL_SERIAL_IER_UUE);

When the serial driver load, after it excuted the above function, there is a
lot of event message print infinitely.

Is there something wrong in my BSP or the hardware itself?

Is your serial port connetced to some hardware (maybe a modem)? It looks
like someone is toggling
some signals

Check that the GPIO pins used for the serial port signals are
configured in the right way (you may use different pins for the
serial port on the PXA and it may be that your board don't use the
same pins the original mainstone II board does).
Check also that you don't have other devices connected to some
serial pins that you considered as unused (you may use FFUART as a
simple TX-RX serial port but you should assign the right alternate
functions to the other pins or set their AF to 0 if they are used
for direct I/O).
Check also that your interrupt handling code cleans-up all the
pending interrupt requests or you may get a new interrupt
immediately after you re-enable it calling InterruptDone.
