The whole Motorola MPC8xx family is adequately identified by the 860 (MPC860,
PPC860 would be a mis-nomer) for GCC purposes (esp. no HW floating point).

Here is my list of processor names that fall into this family: 821, 823, 823e,
850, 850de, 850dsl, 850sr, 852t, 855t, 857dsl, 857t, 859dsl, 859t, 860, 860de,
860dp, 860dt, 860en, 860mh, 860p, 860sar, 860sr, 860t, 862p, 862t, 866p, and
866t.

These are embedded processors with a common CORE CPU (the only relevant portion
for GCC, a Cache/MMU subsystem, and a rich set of internal peripherals, totally
irrelevant to GCC, plus a RISC co-processor for advanced communications protocol
implementation).

The Motorola MPC82xx family is an enhanced version of the above MPC8xx family
(higher speed, floating point, and a streamlined interrupt controller).

There are other PPC implementations for the embedded market, from IBM, Motorla,
and Xilinx as well.

Sincerely,
