This patch introduces the support for dom0less configuration when using UEFI boot on ARM, it permits the EFI boot to continue if no dom0 kernel is specified but at least one domU is found. Introduce the new property "xen,uefi-binary" for device tree boot module nodes that are subnode of "xen,domain" compatible nodes. The property holds a string containing the file name of the binary that shall be loaded by the uefi loader from the filesystem. Introduce a new call efi_check_dt_boot(...) called during EFI boot that checks for module to be loaded using device tree. Architectures that don't support device tree don't have to provide this function. Update efi documentation about how to start a dom0less setup using UEFI Signed-off-by: Luca Fancellu <luca.fancellu@arm.com> [stefano: drop inline from efi_check_dt_boot] Signed-off-by: Stefano Stabellini <stefano.stabellini@xilinx.com> Reviewed-by: Bertrand Marquis <bertrand.marquis@arm.com> Reviewed-by: Stefano Stabellini <sstabellini@kernel.org> Acked-by: Jan Beulich <jbeulich@suse.com>
