Add endianness as io mem parameter
As stated before, devices can be little, big or native endian. Thetarget endianness is not of their concern, so we need to push thingsdown a level.
This patch adds a parameter to cpu_register_io_memory that allows adevice to choose its endianness. For now, all devices simply choose...
intel-hda: fix codec addressing.
The HDA bus supports up to 15 codecs, with addresses 0 ... 14.We get that wrong in two places:

intel-hda: Honor WAKEEN bits.
HDA: Honor WAKEEN bits when deciding to raise an interrupt on codecstatus change. This prevents an interrupt storm with the Haiku HDAdriver which does not handle codec status changes in the irq handler.

intel-hda: add msi support
This patch adds MSI support to the intel hda audio driver. It isenabled by default, use '-device intel-hda,msi=0' to disable it.
[ v2: codestyle: add braces ]
intel-hda: exit cleanup
Add pci exit callback for the intel-hda device and cleanup properly.Also add an exit callback to the HDA bus implementation and make sureit is called on qdev_free().
Add Intel HD Audio support to qemu.
This patch adds three devices to qemu:
intel-hda Intel HD Audio Controller, the PCI device. Provides a HDA bus. Emulates ICH6 at the moment. Adding a ICH9 PCIE variant shouldn't be hard.
hda-duplex HDA Codec. Attaches to the HDA bus. Supports 16bit stereo,...
