You can probably take our 2.4 kernel code as a starting point. But be
aware of the inherent restrictions of the CPM, see
http://www.denx.de/wiki/view/DULG/UseSCCUARTWithHardwareHandshake

[In the end, you might want to configure  the  handshake  signals  as
GPIO lines and controll these manually. But then you will have to ask
yourself why you are using a CPM...]
