Subject: hw/hppa: PCI devices depend on availability of PCI bus
X-Git-Tag: v10.2.0-rc1~42^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=557bc5260cfdb1047290b4c92d1128f93abf6097;p=thirdparty%2Fqemu.git

hw/hppa: PCI devices depend on availability of PCI bus

Only create the PCI serial ports (DIVA) and PCI network cards when there is
actually a PCI bus. The shortly added 715 machine will not have a PCI bus, so
avoid creating further PCI devices.
