From ce5ac09a7548d90ac414f60bbe87c69a8487de10 Mon Sep 17 00:00:00 2001 From: Bernhard Beschow Date: Fri, 30 Jun 2023 09:37:19 +0200 Subject: [PATCH] hw/pci-host/i440fx: Resolve i440fx_init() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit i440fx_init() is a legacy init function. The previous patches worked towards TYPE_I440FX_PCI_HOST_BRIDGE to be instantiated the QOM way. Do this now by transforming the parameters passed to i440fx_init() into property assignments.
