Thank you for your feedback. If I understand correctly, sifive_spi does
not support migration currently. Would it be possible to merge this
QOMification without the migration feature for now, as not all devices
in sifive_u support it at the moment anyways? It seems it would be
difficult to test on my end.
Best regards,
Lukas
