Subject: [PATCH] arm64: dts: fvp: Add SPE to Foundation FVP
Date: Thu, 17 Nov 2022 10:25:36 +0000 [thread overview]
Message-ID: <20221117102536.237515-1-james.clark@arm.com> (raw)
Add SPE DT node to FVP model. If the model doesn't support SPE (e.g.,
turned off via parameter), the driver will skip the initialisation
accordingly and thus is safe.
