From bebc1410ca79f5b8b33ca86b18bd55fd45d13185 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 21 Dec 2022 16:08:22 -0700 Subject: [PATCH] trace: Move trace pointer to data section This can be written before relocation. Move it to the data section, since accessing BSS before relocation is not permitted.
