[Qemu-devel] [PATCH RFC] Generic PCIE-to-PCI Bridge

[Aleksandr Bezzubikov <zuban32s@gmail.com>]

This patch introduces a new device - generic PCI Express to PCI bridge.

Now only x86-specific DMI-to-PCI bridge can be used to enable 
usage of legacy PCI devices on Q35 machine. But this bridge isn't cross-platform 
and doesn't support hotplugging.
That's why we need a new generic cross-platform bridge device, which supports hotplugging.

This patch creates device only for static CLI usage, 
the next goal is to add ACPI hotplug support.  It will utilize 
in some way past Marcel's RFC series for Q35 ACPI PCI hotplug support 
https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg05681.html, 
but will require dynamic ACPI code emission in case when the bridge was hotplugged itself.
