First of all, the 8555 uses FreeScale's TSEC (Triple Speed Ethernet 
Controller) which is
completely different from any of the network drivers in the public CVS.  
Writing such
a driver is not special for the architecture, per se, but rather so for 
the device itself.

You'll also need a PowerPC HAL for the 85xx series of CPU chips.  This 
is also not
in the public CVS and is radically different from any that are (you 
asked privately
about starting from the 8260 code - the 82xx and 85xx are pretty far 
apart and you'll
end up writing most everything over anyway)
