Subject: [PATCH kvmtool 05/16] arm: pci.c: Advertise only PCI bus 0 in the DT
Date: Mon, 25 Nov 2019 10:30:22 +0000	[thread overview]
Message-ID: <20191125103033.22694-6-alexandru.elisei@arm.com> (raw)
In-Reply-To: <20191125103033.22694-1-alexandru.elisei@arm.com>

The "bus-range" property encodes the first and last bus number. kvmtool
uses bus 0 for PCI and bus 1 for MMIO.  Advertise only the PCI bus in
the PCI DT node by setting "bus-range" to <0, 0>.
