At this time, we do not have drivers for the PCMCIA on the MPC8xx.  What we
do have is a generic PCMCIA framework which is split into two parts.  The
piece of interest to you is the hardware driver which manages the actual
chip details.  The only example of a PCMCIA (and Compact Flash - in this case
they are equivalent) hardware driver is for the PCMCIA/CF controller on the
StrongARM SA1110. 

To create PCMCIA support for your device, you would need to write the hardware
driver.  You could model it after the CF driver.  Sadly, at this time the only
documentation for this process is the code itself.
