The 8555 u-boot is different from the 8548 u-boot.  There are also  
differences in the device-tree (I'm not sure what version of the  
kernel is in the BSP, so I can't say for sure).  Recent versions of  
the Linux kernel merged all of the CDS systems into one kernel.

As for the differences, off the top of my head:

* 8555 vs 8548 chip
* PCI slot on the carrier card is PCI on 8555, PCIe on 8548.
* 8548 has 4 eTSECs, 8555 has 2 TSECs (and the # of ethernet ports  
reflects this).
