Several devices of the sun4m machines are using &error_fatal in
their instance_init function and thus can cause QEMU to abort
unexpectedly:
$ echo "{'execute':'qmp_capabilities'}"\
"{'execute':'device-list-properties',"\
" 'arguments':{'typename':'openprom'}}" \
| sparc-softmmu/qemu-system-sparc -M SS-10 -S -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
"package": "build-all"}, "capabilities": []}}
{"return": {}}
RAMBlock "sun4m.prom" already registered, abort!
Aborted (core dumped)
$ echo "{'execute':'qmp_capabilities'}"\
"{'execute':'device-list-properties',"\
" 'arguments':{'typename':'macio_idreg'}}" \
| sparc-softmmu/qemu-system-sparc -M SS-10 -S -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
"package": "build-all"}, "capabilities": []}}
{"return": {}}
RAMBlock "sun4m.idreg" already registered, abort!
Aborted (core dumped)
$ echo "{'execute':'qmp_capabilities'}"\
"{'execute':'device-list-properties',"\
" 'arguments':{'typename':'tcx_afx'}}" \
| sparc-softmmu/qemu-system-sparc -M SS-5 -S -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 91, "minor": 11, "major": 2},
"package": "build-all"}, "capabilities": []}}
{"return": {}}
RAMBlock "sun4m.afx" already registered, abort!
Aborted (core dumped)
Fix the issues by converting the instance_init functions into realize()
functions instead, which are allowed to fail (and not called during
device introspection).
