1 * Xen hypervisor device tree bindings
3 Xen ARM virtual platforms shall have a top-level "hypervisor" node with
7 	compatible = "xen,xen-<version>", "xen,xen";
8   where <version> is the version of the Xen ABI of the platform.
19 - interrupts: the interrupt used by Xen to inject event notifications.
22 To support UEFI on Xen ARM virtual platforms, Xen populates the FDT "uefi" node
28 xen,uefi-system-table     | 64-bit | Guest physical address of the UEFI System
31 xen,uefi-mmap-start       | 64-bit | Guest physical address of the UEFI memory
34 xen,uefi-mmap-size        | 32-bit | Size in bytes of the UEFI memory map
37 xen,uefi-mmap-desc-size   | 32-bit | Size in bytes of each entry in the UEFI
40 xen,uefi-mmap-desc-ver    | 32-bit | Version of the mmap descriptor format.
46 	compatible = "xen,xen-4.3", "xen,xen";
50 		xen,uefi-system-table = <0xXXXXXXXX>;
51 		xen,uefi-mmap-start = <0xXXXXXXXX>;
52 		xen,uefi-mmap-size = <0xXXXXXXXX>;
53 		xen,uefi-mmap-desc-size = <0xXXXXXXXX>;
54 		xen,uefi-mmap-desc-ver = <0xXXXXXXXX>;
58 The format and meaning of the "xen,uefi-*" parameters are similar to those in
60 they differ because they are provided by the Xen hypervisor, together with a set
