Hi, Willy
I'm very sorry, the extra configs/powerpc.config file is missing in this patch, perhaps a failed rebase introduced this issue.
Please don't merge it, to avoid manually merge another addtional patch, if no other issues in this v2 series, I will send v3 immediately, just wait for your feedbacks, no hurry.
Best regards, Zhangjin
The default qemu-system-ppc g3beige machine [1] is used to run 32-bit powerpc kernel.
The pmac32_defconfig is used with extra PMACZILOG console options to enable normal print.
Note, zImage doesn't boot due to "qemu-system-ppc: Some ROM regions are overlapping" error, so, vmlinux is used instead.
Kernel uses ARCH=powerpc for both 32-bit and 64-bit PowerPC, here adds a ppc variant for 32-bit PowerPC and use it as the default variant of powerpc architecture.
Users can pass ARCH=powerpc or ARCH=ppc to test 32-bit PowerPC.
