What else need to be explained apart from that SM501 has an i2c part which is used to access EDID info of attached monitor. But this is what the commit title already says. This patch implements that so far not emulated part of the chip.
[snip]static const VMStateDescription vmstate_sm501_sysbus = { .name = TYPE_SYSBUS_SM501, - .version_id = 1, - .minimum_version_id = 1, + .version_id = 2, + .minimum_version_id = 2, .fields = (VMStateField[]) { VMSTATE_STRUCT(state, SM501SysBusState, 1, vmstate_sm501_state, SM501State),Additionally, since you're changing the migration stream, you need to point out that this is not used in any machine types which support cross-version migration.
AFAIK it is only used in SH4 and PPC sam460ex.
