The PCI support for Xen doesn't compile on ARM/ARM64 when CONFIG_PCI_MMCONFIG=y:
drivers/xen/pci.c:31:25: fatal error: asm/pci_x86.h: No such file or directory #include <asm/pci_x86.h>
Although, Xen is not currently involved in PCI management for ARM/ARM64. There is plan to support it, but it would require some changes in Linux side.
For now, introduce a new config options XEN_PCI which will be turned off for ARM platform.
