SPI on the MPC8541

This is my first time using the mailing list so hello.

I am trying to find a SPI driver.  The SPI is located in the CPM2 block on 
a MPC8541.  I am working with the freescale MPC85xxCDS reference board. 
Could someone point me in the right direction or let me know if I should 
just write my own driver.  All of the SPI code I have found seems to just 
use a serial port, parallel port or bit bang the data out a GPIO.  I want 
a driver that uses the registers that are available to me.

Thanks,
Gabe
