Linux documents it in Documentation/devicetree/bindings/riscv/cpus.yaml as: riscv,cbom-block-size: $ref: /schemas/types.yaml#/definitions/uint32 description: The blocksize in bytes for the Zicbom cache operations. cboz-block-size has the same role but for the Zicboz extension, i.e. informs the size in bytes for Zicboz cache operations. Linux support for it is under review/approval in [1]. Patch 3 of that series describes cboz-block-size as: riscv,cboz-block-size: $ref: /schemas/types.yaml#/definitions/uint32 description: The blocksize in bytes for the Zicboz cache operations.
