The problem is that this is inconsistent with most Kconfig options.
Last I heard, the kernel community generally frowns on "default y" in
Kconfig options.

I'm waiting for someone to explain to me what's so special about CHRP
and PMAC that these two platforms should be enabled by default, when
all other PowerPC platforms are disabled by default.

This is what I see in menuconfig when I create a fresh .config for PowerPC:

  │ │    [*] Common Hardware Reference Platform (CHRP) based machines (NEW)
  │ │    [ ] Freescale MPC5121E ADS (NEW)
  │ │    [ ] Generic support for simple MPC5121 based boards (NEW)
  │ │    [ ] 52xx-based boards (NEW)
  │ │    [*] Apple PowerMac based machines (NEW)
  │ │    [ ] 82xx-based boards (PQ II) (NEW)  --->
  │ │    [ ] 83xx-based boards (NEW)  --->
  │ │    [ ] 86xx-based boards (NEW)  --->
  │ │    [ ] Embedded 6xx/7xx/7xxx-based boards (NEW)

CHRP and PMAC aren't following the rules that everyone else is following.  Why?
