xen: add CONFIG_XEN_BUS and CONFIG_XEN_EMU options for Xen emulation
The XEN_EMU option will cover core Xen support in target/, which exists only for x86 with KVM today but could theoretically also be implemented on Arm/Aarch64 and with TCG or other accelerators (if anyone wants to run the gauntlet of struct layout compatibility, errno mapping, and the rest of that fui). It will also cover the support for architecture-independent grant table and event channel support which will be added in hw/i386/kvm/ (on the basis that the non-KVM support is very theoretical and making it not use KVM directly seems like gratuitous overengineering at this point). The XEN_BUS option is for the xenfv platform support, which will now be used both by XEN_EMU and by real Xen. The XEN option remains dependent on the Xen runtime libraries, and covers support for real Xen. Some code which currently resides under CONFIG_XEN will be moving to CONFIG_XEN_BUS over time as the direct dependencies on Xen runtime libraries are eliminated. The Xen PCI platform device will also reside under CONFIG_XEN_BUS. Signed-off-by: David Woodhouse <dwmw@amazon.co.uk> Reviewed-by: Paul Durrant <paul@xen.org>
