Hi , Could you please tell me which processor I should take as baseline in order to port eCos on MPC8555.

Is the code is different for different board and different processor.?
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)
