From 7cf236cf1f7d6b6aa2a860a1a80ad99df46b9144 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Fri, 24 Jun 2022 14:14:59 +0200 Subject: [PATCH] microblaze: Switch absolute branches to relative There is no reason to use absolute branches and use just relative. This change helps with moving binary to different location and start it from there.
