+ XenIo protocol to abstract arch specific details
+
+ The Xen implementations for the Intel and ARM archictures differ in the way
+ the base address of the grant table is communicated to the guest. The former
+ uses a virtual PCI device, while the latter uses a device tree node.
+ In order to allow the XenBusDxe UEFI driver to be reused for the non-PCI
+ Xen implementation, this abstract protocol can be installed on a handle
+ with the appropriate base address.
