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
