Subject: [PATCH 2/3] ARM: footbridge: avoid using separate PCI I/O bus resource
Date: Fri, 26 Mar 2021 12:18:13 +0000 [thread overview]
Message-ID: <E1lPlPp-0007oR-7A@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20210326121735.GQ1463@shell.armlinux.org.uk>
Disable the separate PCI I/O bus resource, since the PCI bus on these
platforms covers the whole of I/O space, even low ISA addresses are
on the PCI bus.
