From 0063454affb3c5a595539a3cad9e20e7229d8fac Mon Sep 17 00:00:00 2001 From: =?utf8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Sat, 2 Feb 2019 20:48:46 +0100 Subject: [PATCH] hw/pci-host/piix: Move RCR_IOPORT register definition MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The RCR_IOPORT register belongs to the PIIX chipset. Move the definition to "piix.h", and prepend the PIIX prefix.
