Subject: [PATCH 1/6] PciHostBridge: io range is not mandatory
Date: Thu, 16 Dec 2021 10:50:32 +0100 [thread overview]
Message-ID: <20211216095037.1843149-2-kraxel@redhat.com> (raw)
In-Reply-To: <20211216095037.1843149-1-kraxel@redhat.com>
io range is not mandatory according to pcie spec,
so allow bridge configurations without io address
space assigned.
