PowerPC kernel developers were after a userspace for testing 32-bit
powerpc kernels. This machine both suits that requirement and has
support in qemu. It's also a fairly common piece of 32-bit ppc hardware.

You forgot to specify the version of the Linux kernel /
kernel-headers. Committed with those set to 5.2.4, thanks.
With that said, we now have 4 32bit ppc qemu defconfigs which sounds
like a lot to me. Are they all still interesting / useful?
cd configs && ls qemu_ppc_*
qemu_ppc_g3beige_defconfig
qemu_ppc_mac99_defconfig
qemu_ppc_mpc8544ds_defconfig
qemu_ppc_virtex_ml507_defconfig

I didn't forget, I omitted them so the config would use the latest default.
Is there a reason we specify a fixed version?

I am not familiar with them. Michael?
They all target different CPUs which means there is no overlap at least:
$ grep -r BR2_powerpc_ configs/qemu_ppc_*
configs/qemu_ppc_g3beige_defconfig:BR2_powerpc_750=y
configs/qemu_ppc_mac99_defconfig:BR2_powerpc_7400=y
configs/qemu_ppc_mpc8544ds_defconfig:BR2_powerpc_8548=y
configs/qemu_ppc_virtex_ml507_defconfig:BR2_powerpc_440=y
Cheers,
Joel

Yes, reproducibility. If the defconfig is tested and working today, then
it should preferably still work in (say) 6 months from now.

Correct. Ok, lets leave them for now then.

So do we ;)
ls configs/*_defconfig | wc -l
213

Ok, lets just leave them for now. Thanks!
