Subject: [PATCH v4 13/28] arm64/sysreg: Standardise naming for ID_AA64PFR0_EL1 constants
Date: Thu, 18 Aug 2022 13:24:10 +0100	[thread overview]
Message-ID: <20220818122425.37889-14-broonie@kernel.org> (raw)
In-Reply-To: <20220818122425.37889-1-broonie@kernel.org>

We generally refer to the baseline feature implemented as _IMP so in
preparation for automatic generation of register defines update those for
ID_AA64PFR0_EL1 to reflect this.

In the case of ASIMD we don't actually use the define so just remove it.

No functional changes.
