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. | |
