[Qemu-ppc] [PATCHv3 00/12] macio: remove legacy macio_init() function

From: Mark Cave-Ayland
Subject: [Qemu-ppc] [PATCHv3 00/12] macio: remove legacy macio_init() function
Date: Wed, 28 Feb 2018 20:32:31 +0000

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.

- Rebase onto master
- Add extra R-B tags from David and Philippe
- Add patch 8 to move KVM openpic declarations into separate openpic_kvm.h file
  (fixes compilation of ppc-linux-user)

- Rebase onto master
- Add R-B tags from David
- Rework patch 4 ("heathrow: convert to trace-events") as suggested by David

Mark Cave-Ayland (12):
  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
  mac_oldworld: use object link to pass heathrow PIC object to macio
  openpic: move KVM-specific declarations into separate openpic_kvm.h
  openpic: move OpenPIC state and related definitions to openpic.h
  mac_newworld: use object link to pass OpenPIC object to macio
  macio: move setting of CUDA timebase frequency to
  macio: remove macio_init() function
