sparc32 defconfig+CONFIG_SQUASHFS=y+CONFIG_DEVTMPFS=y, and:

qemu-system-sparc -M SPARCClassic -kernel arch/sparc/boot/image \
	-no-reboot -snapshot -drive file=/var/cache/buildbot/sparc/hda.sqf,if=scsi,format=raw \
	-append 'root=/dev/sda rw init=/sbin/init.sh panic=1 console=ttyS0' \
	-nographic

qemu version doesn't seem to matter. I used gcc-7.3.0 using the toolchain from kernel.org
to build the image.

Root file system is at https://github.com/groeck/linux-build-test/tree/master/rootfs/sparc/.
