Define a new protocol for loading and starting images, encapsulating shim's PE loading facilities and verification/authentication against the same set of certificates that shim_lock::verify() authenticates against. This removes the need for loaders like GRUB to implement their own PE loader in order to be able to invoke loaded images as PE applications, rather than implementing a bespoke OS dependent handover protocol (e.g., invoke Linux via its EFI stub) Signed-off-by: Ard Biesheuvel <[email protected]>
Currently the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL and EFI_LOAD_FILE2_PROTOCOL are supported. Signed-off-by: Mate Kukri <[email protected]>
This will bring SBAT enforcement in-line with the shim_lock protocol. Signed-off-by: Mate Kukri <[email protected]>

This rebases the current loader protocol work on main and adds support for loading executables if only a device path is provided. Currently the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL and EFI_LOAD_FILE2_PROTOCOL are supported, which should be sufficient for most users.
