[PATCH v3 11/17] xen/arm: PCI host bridge discovery within XEN on ARM

2021-09-28 Thread Rahul Singh
XEN during boot will read the PCI device tree node “reg” property and will map the PCI config space to the XEN memory. As of now only "pci-host-ecam-generic" compatible board is supported. "linux,pci-domain" device tree property assigns a fixed PCI domain number to a host bridge, otherwise an uns
