Subject: hw/loongarch/virt: Add field gpex in LoongArchVirtMachineState
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=efee88883a7e26e158ee498b7f5f1674505618ba;p=thirdparty%2Fqemu.git

hw/loongarch/virt: Add field gpex in LoongArchVirtMachineState

Add field gpex in structure LoongArchVirtMachineState, type of field gpex
is structure GPEXConfig and it is to record configuration information
about GPEX host bridge. And remove field pci_bus in structure
LoongArchVirtMachineState since the information is in field gpex already.
