/** @file
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.
