There is no device-tree with compatible "u-boot,efi-bootmgr". So this looks like dead code up to now. Please, provide a unit test.
@Simon Where is the documentation that describes the "u-boot,distro-efi" and "u-boot,efi-bootmgr" boot methods? Current doc/device-tree-bindings/bootmeth.txt is not sufficient and not included in the generated online documentation.
doc/device-tree-bindings/bootmeth.txt should be converted to yaml format so that it can be used for validation of device-trees.
