Hello,
Commit 18a536f1f8 (accel/tcg: Always require can_do_io) broke booting
MorphOS on sam460ex (this was before 8.2.0 and I thought I've verified
it before that release but apparently missed it back then). It can be
reproduced with https://www.morphos-team.net/morphos-3.18.iso and
following command:
qemu-system-ppc -M sam460ex -serial stdio -d unimp,guest_errors \
-drive if=none,id=cd,format=raw,file=morphos-3.18.iso \
-device ide-cd,drive=cd,bus=ide.1

Not sure what it's trying to do here, maybe decompressing some code and
then trying to execute it? Any idea what could be the problem or what to
check further?
