From f60854369a921bf778b587f65d458987d326a4a0 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Fri, 6 May 2022 16:18:33 +0200 Subject: [PATCH 1/3] dt-bindings: riscv: document cbom-block-size The Zicbom operates on a block-size defined for the cpu-core, which does not necessarily match other cache-sizes used. So add the necessary property for the system to know the core's block-size.
