Subject: [PATCH v3 1/2] arm64/sysreg: Move TRFCR definitions to sysreg
Date: Tue,  5 Sep 2023 11:21:14 +0100	[thread overview]
Message-ID: <20230905102117.2011094-2-james.clark@arm.com> (raw)
In-Reply-To: <20230905102117.2011094-1-james.clark@arm.com>

Add separate definitions for ELx and EL2 as TRFCR_EL1 doesn't have CX.
This also mirrors the previous definition so no code change is required.
