[PATCH v2 0/3] dt-bindings: riscv: Add RISC-V Worlds and SiFive WorldGuard DT bindings

[Yu-Chien Peter Lin]

Add device tree bindings for RISC-V Worlds, a standard extension that tags
every transaction with a World ID for fine-grained isolation. SiFive's
WorldGuard Checker is a hardware firewall in the system interconnect that
inspects transaction WIDs and enforces per-World access policies on memory
and MMIO devices.
