From 6e4aceba2079e3df42edc89d44f4ee02343bb09e Mon Sep 17 00:00:00 2001 From: BALATON Zoltan Date: Thu, 11 Apr 2024 21:24:43 +0200 Subject: hw/pci-host/ppc440_pcix: Do not expose a bridge device on PCI bus MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Real 460EX SoC apparently does not expose a bridge device and having it appear on PCI bus confuses an AmigaOS file system driver that uses this to detect which machine it is running on.
