[PATCH 2/4] dt-bindings: riscv: document cbom-block-size

From: Heiko Stuebner
Date: Sun Jun 19 2022 - 16:32:40 EST


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.
