Commit Message

Zhangjin Wu July 18, 2023, 9:16 p.m. UTC 
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.
