efi_loader: Add runtime services
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. Signed-off-by: Alexander Graf <> Reviewed-by: Simon Glass <> Tested-by: Simon Glass <>
