From c428ca80c298df55db242571d868dae7b475ccb5 Mon Sep 17 00:00:00 2001 From: Ye Li Date: Thu, 25 Mar 2021 17:30:06 +0800 Subject: imx: hab: Add function to authenticate kernel image When loading kernel image, the image size is parsed from header, so it does not include the CSF and IVT. Add back the authenticate_image function to wrap the imx_hab_authenticate_image with calculating IVT offset and full image size.
