If I understand correctly, later Power Macs and IBM Power systems are
compatible with CHRP, and that is the only platform supported.  But I
don't think the term CHRP is widely understood so there is little point
in mentioning it.

However, there are separate powerpc and powerpc64 subarchitectures
because (if I remember correctly) 32-bit kernels won't run on 64-bit
firmware.

Starting with Linux 4.7 we are not building kernels for them.

Also, there are no installer builds with the 5kc-malta kernel flavour, since the 4kc-malta flavour runs on all the same hardware.

You didn't ask about ARM and x86, but:

- On armel, kirkwood and orion5x are still separate subarchitectures
  even though they use the same kernel flavour
- On armhf, there is no armmp-lpae subarchitecture, because all
  hardware that can run the armmp-lpae kernel can also run the armmp
  kernel
- On i386, there is a separate 'xen' subarchitecture for Xen PV
  domains, using the 686-pae kernel flavour
