-/** @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.
