1. Install FreeBSD-12.0-RELEASE in qemu-system-powerpc64
Use GPT partition scheme, all recommended options.
2. Boot installed system
qemu versions tested: 4.0.0rc1, 3.0.0 on Mac OS X intel in full emulation,
2.11.1 on POWER8 (Ubuntu 18.04, with KVM)
All quemu versions come with different SLOF versions, all fail.
Even a fresh compiled SLOF image from qemu/slof failed.
During testing, it turned out that the loader tries 16 partitions on the given boot device but fsread() fails to read or identify the UFS superblock on partition 2.
I don't know what component is failing: qemu, slof, or boot1.elf
