The current EFI implementation has a strange quirk where it watches loaded files and uses the last-loaded file to determine the device that is being booted from.
This is confusing with bootstd, where multiple options may exist. Even loading a device tree will cause it to go wrong. There is no API for passing this information, since the only entry into booting an EFI image is the 'bootefi' command.
To work around this, call efi_set_bootdev() for EFI images, if possible, just before booting.

Shouldn't this all be a simple wrapper around the EFI Standard BootDeviceOrder or whatever that's called?
