sysbus_add_io(...) is a simple wrapper to
memory_region_add_subregion(get_system_io(), ...).
It is used in 3 places; inline it directly.

Rationale here is we want to move to an explicit I/O bus, rather that an implicit one. Besides in heterogeneous setup we can have more than one I/O bus. > Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> > --- > include/hw/sysbus.h | 2 -- > hw/core/sysbus.c | 6 ------ > hw/i386/kvmvapic.c | 2 +- > hw/mips/mipssim.c | 2 +- > hw/nvram/fw_cfg.c | 5 +++-- > 5 files changed, 5 insertions(+), 12 deletions(-) > > diff --git a/include/hw/sysbus.h b/include/hw/sysbus.h > index 3564b7b6a2..14dbc22d0c 100644 > --- a/include/hw/sysbus.h > +++ b/include/hw/sysbus.h > @@ -83,8 +83,6 @@ void sysbus_mmio_map(SysBusDevice *dev, int n, hwaddr addr); > void sysbus_mmio_map_overlap(SysBusDevice *dev, int n, hwaddr addr, > int priority); > void sysbus_mmio_unmap(SysBusDevice *dev, int n); > -void sysbus_add_io(SysBusDevice *dev, hwaddr addr, > - MemoryRegion *mem); > MemoryRegion *sysbus_address_space(SysBusDevice *dev);
