Subject: [PATCH v5 5/8] arm64: dts: morello: Add support for common functionalities
Date: Thu, 13 Feb 2025 18:03:06 +0000 [thread overview]
Message-ID: <20250213180309.485528-6-vincenzo.frascino@arm.com> (raw)
In-Reply-To: <20250213180309.485528-1-vincenzo.frascino@arm.com>
The Morello architecture is an experimental extension to Armv8.2-A,
which extends the AArch64 state with the principles proposed in
version 7 of the Capability Hardware Enhanced RISC Instructions
(CHERI) ISA.
The Morello Platform (soc) and the Fixed Virtual Platfom (fvp) share
some functionalities that have conveniently been included in
morello.dtsi to avoid duplication.
Introduce morello.dtsi.
Note: Morello fvp will be introduced with a future patch series.
