[Qemu-devel] [PATCH 1/4] hw/pxb: remove the built-in pci bridge |
Date: |
Thu, 12 Nov 2015 17:11:13 +0200 |
As part of porting the pxb device to Q35 remove the internal pci-2-pci
bridge. The only way to hot-pug devices on the extra PCI root buses
is by adding a pci-2-pci to the pxb before the firmware assign the
IO/mem resources.
