[PATCH v3 3/4] arm64: dts: morello: Add support for soc dts

From: Vincenzo Frascino
Date: Thu Jan 02 2025 - 10:55:15 EST


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.

Introduce Morello SoC dts.
