[PATCH v19 1/5] hw/arm/virt: Introduce a RAS machine option


From: Xiang Zheng
Subject: [PATCH v19 1/5] hw/arm/virt: Introduce a RAS machine option
Date: Tue, 15 Oct 2019 22:01:36 +0800

From: Dongjiu Geng <address@hidden>

RAS Virtualization feature is not supported now, so add a RAS machine
option and disable it by default.
