    Subject[PATCH 5.4 373/389] riscv: dts: sifive: Add fu540 topology information
    Date
    From: Conor Dooley <conor.dooley@microchip.com>

    [ Upstream commit af8f260abc608c06e4466a282b53f1e2dc09f042 ]

    The fu540 has no cpu-map node, so tools like hwloc cannot correctly
    parse the topology. Add the node using the existing node labels.
