MPC5200 SPI interface.

Hi all,
We are developping a Lite5200B based custom board and we are planning to 
connect some SPI peripherals. But we are not sure about what MPC5200 SPI 
interface choose.  Does anyone know what are the 
advantages/disadvantages of use the MPC5200 SPI dedicated interface or  
an PSC (PSC3) as the SPI interface?. The linux kernel includes both 
interfaces but we can not see in the documentation anything about this 
aspect. Any kind of information will be welcomed.

Best Regards,
José María López.
