From 99d6e739324ff1be46ad89a2682978cc1fa3a56c Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Thu, 20 Jun 2024 16:59:28 +0200 Subject: [PATCH 05/27] hw/s390x: Remove the possibility to load the s390-netboot.img binary MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit RH-Author: Thomas Huth RH-MergeRequest: 277: Full boot order support for s390x [CentOS 9] RH-Jira: RHEL-11424 RH-Acked-by: Cédric Le Goater RH-Acked-by: Miroslav Rezanina RH-Commit: [5/23] e4e037f24be08626c02f8e870992e8f0a5ed505e (thuth/qemu-kvm-cs9) Since the netboot code has now been merged into the main s390-ccw.img binary, we don't need the separate s390-netboot.img anymore. Remove it and the code that was responsible for loading it.
