[Qemu-ppc] [PATCHv2 00/11] macio: remove legacy macio_init() function

[Mark Cave-Ayland]

This patchset eliminates the legacy macio_init() function used to setup the
ESCC and PIC memory regions and instead allows the macio device to be
instantiated directly via qdev, wiring up the ESCC internally using sysbus MMIO
memory regions and the PIC via QOM object links.

The biggest surprise in this patchset was the need to QOMify the heathrow
device which apparently up until now has never required any of these new-fangled
APIs from the last decade such as qdev and QOM.

There's still some follow-up work to do with the PCI host bridge wiring but it
seems to me that this is a good preparation step.

Mark Cave-Ayland (11):
  macio: embed DBDMA device directly within macio
  macio: move ESCC device within the macio device
  heathrow: QOMify heathrow PIC
  heathrow: convert to trace-events
  heathrow: change heathrow_pic_init() to return the heathrow device
  macio: move macio related structures and defines into separate macio.h
    file
  mac_oldworld: use object link to pass heathrow PIC object to macio
  openpic: move OpenPIC state and related definitions to openpic.h
  mac_newworld: use object link to pass OpenPIC object to macio
