From a0ca51f70b7559733c65cef1069f1b39aa410a0f Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Fri, 18 Mar 2022 00:00:45 -0500 Subject: [PATCH] sunxi: Support building a SPL as a TOC0 image Now that mkimage can generate TOC0 images, and the SPL can interpret them, hook up the build infrastructure so the user can choose which image type to build. Since the absolute load address is stored in the TOC0 header, that information must be passed to mkimage.
