[PATCH 0/5] RISC-V: Add cpu-map topology information nodes

From: Conor Dooley <conor.dooley at microchip.com>

It was reported to me that the Hive Unmatched incorrectly reports
its topology to hwloc, but the StarFive VisionFive did in [0] &
a subsequent off-list email from Brice (the hwloc maintainer).
This turned out not to be entirely true, the /downstream/ version
of the VisionFive does work correctly but not upstream, as the
downstream devicetree has a cpu-map node that was added recently.

This series adds a cpu-map node to all upstream devicetrees, which
I have tested on mpfs & fu540. The first patch is lifted directly
from the downstream StarFive devicetree.

Thanks,
Conor.
