* remotes/mcayland/tags/qemu-sparc-20201028:
  hw/pci-host/sabre: Simplify code initializing variable once
  hw/pci-host/sabre: Remove superfluous address range check
  hw/pci-host/sabre: Update documentation link
  sabre: increase number of PCI bus IRQs from 32 to 64
  hw/display/tcx: Allow 64-bit accesses to framebuffer stippler and blitter
  sabre: don't call sysbus_mmio_map() in sabre_realize()
  sparc32-ledma: don't reference nd_table directly within the device
  sparc32-espdma: use object_initialize_child() for esp child object
  sparc32-ledma: use object_initialize_child() for lance child object
  sparc32-dma: use object_initialize_child() for espdma and ledma child objects
