From dc6b3f5ae020c950e12a97ef4e3baca21e027e08 Mon Sep 17 00:00:00 2001 From: Stefan Berger Date: Tue, 21 Jan 2020 15:01:41 -0500 Subject: slof: Make linker script variables accessible Make linker script variables related to 'text' addresses available to the code so we can measure the static core root of trust contents. When hashing the 'data' part of SLOF we do not end up with the same measurements for the same firmware when booting with different configurations, so we don't make those available.
