[Qemu-devel] [PATCH v4 0/8] qdev'ify PReP PCI host bridge and add PCI-to-ISA bridge

["Andreas Färber" <andreas.faerber@web.de>]

Hello,

Here's an improved initial qdev'ification series for PReP, as prerequisite
for Anthony's second QOM series.

On Jan's suggestion, the i8259 IRQs are exposed through qdev GPIO-in IRQs on
the i82378 PCI->ISA bridge

Regards,
Andreas

Changes since v3:
* i82378: Add i8259 IRQs as state and provide qdev GPIO-in access to them.
* prep: Update wiring of IRQs. Both suggested by Jan.

Changes since v2:
* Simplify I/O byte swaps.
* Convert I/O from old_mmio to MemoryRegion ops.
* Drop pci_prep_init() and instantiate the PCI host bridge in the machine,
  reintroducing PREPPCIState extension.
* Connect IRQs via qdev after instantiating. Suggested by Alex.
* Add a rebased PCI-to-ISA-bridge from the 40P series on top, to show why
  some suggestions from v2 and IRC don't work out.
  * Merge fix-up by Hervé: Add indirection for late-connected out[0] IRQ.
  * Add VMState for i82374 and i82378.
  * From i82378 drop the I/O address translation duplicated from the board.
  * Rebase i82378 onto Memory API.

* Add new patch from Hervé to wire up the PCI-to-ISA bridge for 'prep'.

Changes since v1:
* Use the new .vendor_id etc. in PCIDeviceInfo
* Rename from PRePPCI to Raven, adopt naming scheme from i440FX
* Rebase onto multiple Memory API conversions
* Split into PCIDevice and SysBus patches, leave out PREPPCIState changes
