Subject: [PATCH 4/5] riscv: dts: microchip: Add mpfs' topology information
Date: Tue, 5 Jul 2022 20:04:35 +0100 [thread overview]
Message-ID: <20220705190435.1790466-5-mail@conchuod.ie> (raw)
In-Reply-To: <20220705190435.1790466-1-mail@conchuod.ie>
From: Conor Dooley <conor.dooley@microchip.com>
The mpfs has no cpu-map node, so tools like hwloc cannot correctly
parse the topology. Add the node using the existing node labels.
Reported-by: Brice Goglin <Brice.Goglin@inria.fr>
