Isaku Yamahata 5256d8bfad pci: use devfn for pci_find_device() instead of (slot, fn) pair
(slot, fn) pair is somewhat confusing because of ARI.
So use devfn for pci_find_device() instead of (slot, fn).

Alexander Graf 2507c12ab0 Add endianness as io mem parameter
As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.

This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

Michael S. Tsirkin 4677d8ed9d pci: simplify (pci_/pcie_mmcfg_)data_read()
Remove switch on length: we don't care about
high bits for value, so just return all ones
if no device.  And add one assert().

This patch adds common routines for pcie host bridge and pcie mmcfg.
This will be used by q35 based chipset emulation.
