This series looks good to me, but I've not been able to successfully
get qemu to boot anything on SuperH (it just seems to hang with no
output).
Is there anything like magic config or firmware images (I didn't think
so for r2d: shix prints out an error, though) required to get this
going?
The qemu command KUnit is using seems correct (and none of the obvious
permutations, particularly around the serial ports seem to help):
qemu-system-sh4 -nodefaults -m 1024 -kernel .kunit/arch/sh/boot/zImage
-append 'kunit.enable=1 console=ttySC1 kunit_shutdown=reboot'
-no-reboot -nographic -serial null -machine r2d -serial mon:stdio
