hw/ppc: SysBus simplifications

Hi, There is no point in exposing an internal MMIO region via SysBus and directly mapping it in the very same device. This series replaces a sequence of: - sysbus_init_mmio() - sysbus_mmio_map() by a single call to memory_region_add_subregion(). Since v1: - New "Realize SPAPR_VIO_BRIDGE device before accessing it" patch - Added R-b tags Philippe Mathieu-Daudé (7): hw/ppc/spapr_vio: Realize SPAPR_VIO_BRIDGE device before accessing it hw/ppc/pnv_xscom: Rename pnv_xscom_realize(Error **) -> pnv_xscom_init() hw/ppc/pnv_xscom: Move sysbus_mmio_map() call within pnv_xscom_init() hw/ppc/pnv_xscom: Do not use SysBus API to map local MMIO region hw/ppc/pnv: Do not use SysBus API to map local MMIO region hw/intc/spapr_xive: Move sysbus_init_mmio() calls around hw/intc/spapr_xive: Do not use SysBus API to map local MMIO region include/hw/ppc/pnv_xscom.h | 2 +- hw/intc/spapr_xive.c | 12 ++++++------ hw/ppc/pnv.c | 26 +++++--------------------- hw/ppc/pnv_xscom.c | 5 ++--- hw/ppc/spapr_vio.c | 3 ++- 5 files changed, 16 insertions(+), 32 deletions(-)
