From a92771ce8dd5b217ae59c3654d39963e1bd27f95 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Wed, 18 Oct 2023 07:48:11 +0200 Subject: [PATCH] hw/ppc/pnv: Do not use SysBus API to map local MMIO region MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is no point in exposing an internal MMIO region via SysBus and directly mapping it in the very same device. Just map it without using the SysBus API.
