From ee62ab3f309100ebf62979cad11446ae79c7b488 Mon Sep 17 00:00:00 2001 From: Chris Kay Date: Fri, 6 Jan 2023 11:02:00 +0000 Subject: [PATCH] build(bl1): sort sections by alignment by default This change forces LD to sort all input sections by alignment when allocating them within an output section. This is done in some places explicitly in the linker scripts today, but this makes sure we don't miss any easy targets.
