From what I have gained now, PPC970 is apparently maintained in a separate directory, so PowerPC Macintoshes should be fine. Not sure about the Freescale stuff at the moment.
Reading on github https://github.com/torvalds/linux/blob/master/arch/powerpc/kernel/cputable.c support for POWER4 and POWER4+ was removed, but PPC970, PPC970FX et al. is still left. Support for the 64-bit Freescale cpus e5500 and e6500 is also still there.
To answer my question from earlier today, support for 32-bit powerpc seems to be unchanged.
