Yes. IIRC correctly this is code that originally came from Intel's "Tiano" EFI implementation that evolved into EDK and EDKII and other projects under the TianoCore umbrella. At the point in time that code was taken by FreeBSD it was licensed under the license in the README quoted above. It has been relicensed a few times under a BSD-2-Clause and BSD-2-Clause-Patent license. > (I'm not sure efi.h really has anything copyrightable in anyway though?) Well, most of the other headers carry the same notice. The headers themselves are certainly copyrightable. But all they provide is the UEFI interface definitions. So it could be argued that no actual code under this license ends up in our EFI boot loader. We should probably replace this code with something newer at some point. Not only because of the somewhat obscure license but also because we'll need newer UEFI features at some point. For the kernel we already have <dev/efi/efi.h>. Extending that one to include the bits that we use in our EFI bootloaders shouldn't be too much work. Cheers, Mark
