Subject: [PATCH v2 10/16] coresight: Move struct coresight_trace_id_map to common header
Date: Tue,  4 Jun 2024 15:30:19 +0100
Message-Id: <20240604143030.519906-11-james.clark@arm.com>
In-Reply-To: <20240604143030.519906-1-james.clark@arm.com>
References: <20240604143030.519906-1-james.clark@arm.com>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

The trace ID maps will need to be created and stored by the core and
Perf code so move the definition up to the common header.
