Subject: [PATCH v2 2/6] dt-bindings: riscv: Document cboz-block-size
Date: Sun, 22 Jan 2023 20:13:24 +0100	[thread overview]
Message-ID: <20230122191328.1193885-3-ajones@ventanamicro.com> (raw)
In-Reply-To: <20230122191328.1193885-1-ajones@ventanamicro.com>

The Zicboz 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.
