u-boot.git/lib/efi_loader/efi_runtime.c, branch v2016.05-rc1 Unnamed repository; edit this file 'description' to name the repository. efi_loader: Add runtime services 2016-03-15T22:03:10+00:00 Alexander Graf agraf@suse.de 2016-03-04T00:10:01+00:00 50149ea37a21dcbed675297f1536c31a7db39c19 After booting has finished, EFI allows firmware to still interact with the OS using the "runtime services". These callbacks live in a separate address space, since they are available long after U-Boot has been overwritten by the OS. This patch adds enough framework for arbitrary code inside of U-Boot to become a runtime service with the right section attributes set. For now, we don't make use of it yet though. We could maybe in the future map U-boot environment variables to EFI variables here.

We could maybe in the future map U-boot environment variables to EFI variables
here.
