Subject: [PATCH v5 1/6] MdeModulePkg/PciHostBridge: io range is not mandatory
Date: Fri, 22 Apr 2022 09:37:08 +0200 [thread overview]
Message-ID: <20220422073713.2087781-2-kraxel@redhat.com> (raw)
In-Reply-To: <20220422073713.2087781-1-kraxel@redhat.com>
io range is not mandatory according to pcie spec,
so allow bridge configurations without io address
space assigned.
