From c8d8ef00a121ee7326c87a76cc9f49716ed68917 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 7 May 2019 12:55:01 +0100 Subject: [PATCH] pc: Rearrange pc_system_firmware_init()'s legacy -drive loop MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The loop does two things: map legacy -drive to properties, and collect all the backends for use after the loop. The next patch will factor out the former for reuse in hw/arm/virt.c. To make that easier, rearrange the loop so it does the first thing first, and the second thing second.
