They should be desysbusified then can be converted to realize. Out of scope of this series though. * Device Realize functions (incl a few SoCs). In these cases we should propagate for the sake of hotplug failure (or other reasons). I have flagged the easy ones below. * Common helper functions that are missing Error ** even though their callers have them. We should added them (particular in VGA). I think we should try and get the realize and helper ones right and do the machine init and SBD::init ones later. > 62 files changed, 110 insertions(+), 101 deletions(-) > > diff --git a/hw/arm/armv7m.c b/hw/arm/armv7m.c > index c6eab6d..40334d7 100644 > --- a/hw/arm/armv7m.c > +++ b/hw/arm/armv7m.c > @@ -229,7 +229,7 @@ qemu_irq *armv7m_init(MemoryRegion *system_memory, int > mem_size, int num_irq, > /* Hack to map an additional page of ram at the top of the address > space.
