The way u-boot works with almost all the other targets is that if there is no boot script found it will search for efi. This is not the case with nitrogen6x/sabre lite. There was a proposed patch for this but it wasn't committed: http://lists.denx.de/pipermail/u-boot/2016-June/259025.html So we likely want the following patch for now. This will still require a version of u-boot that has bootefi.
