Subject: [PATCH v2 13/38] arm64/sysreg: Standardise naming for MVFR0_EL1
Date: Wed, 30 Nov 2022 17:16:12 +0000	[thread overview]
Message-ID: <20221130171637.718182-14-james.morse@arm.com> (raw)
In-Reply-To: <20221130171637.718182-1-james.morse@arm.com>

To convert the 32bit id registers to use the sysreg generation, they
must first have a regular pattern, to match the symbols the script
generates.

Ensure symbols for the MVFR0_EL1 register use lower-case for feature
names where the arm-arm does the same.

No functional change.
