-===================
-RISC-V CPU Bindings
-===================
-
-The device tree allows to describe the layout of CPUs in a system through
-the "cpus" node, which in turn contains a number of subnodes (ie "cpu")
-defining properties for every cpu.
-
-Bindings for CPU nodes follow the Devicetree Specification, available from:
-
-https://www.devicetree.org/specifications/
-
-with updates for 32-bit and 64-bit RISC-V systems provided in this document.
-
-===========
-Terminology
-===========
-
-This document uses some terminology common to the RISC-V community that is not
-widely used, the definitions of which are listed here:
-
-* hart: A hardware execution context, which contains all the state mandated by
- the RISC-V ISA: a PC and some registers. This terminology is designed to
- disambiguate software's view of execution contexts from any particular
- microarchitectural implementation strategy. For example, my Intel laptop is
- described as having one socket with two cores, each of which has two hyper
- threads. Therefore this system has four harts.
-
-=====================================
-cpus and cpu node bindings definition
-=====================================
-
-The RISC-V architecture, in accordance with the Devicetree Specification,
-requires the cpus and cpu nodes to be present and contain the properties
-described below.

- Description: Container of cpu nodes
-
- The node name must be "cpus".

- Definition: must be set to 1
- - #size-cells
