This patch series adds the cpu topology for RISC-V. It contains
both the DT binding and actual source code. It has been tested on
QEMU & Unleashed board. 

The idea is based on cpu-map in ARM with changes related to how
we define SMT systems. The reason for adopting a similar approach
to ARM as I feel it provides a very clear way of defining the
topology compared to parsing cache nodes to figure out which cpus
share the same package or core.  I am open to any other idea to
implement cpu-topology as well.

Atish Patra (2):
  dt-bindings: topology: Add RISC-V cpu topology.
  RISC-V: Introduce cpu topology.
