Subject: [PATCH v4 05/15] arm64: crypto: Use CC_FLAGS_FPU for NEON CFLAGS
Date: Fri, 29 Mar 2024 00:18:20 -0700	[thread overview]
Message-ID: <20240329072441.591471-6-samuel.holland@sifive.com> (raw)
In-Reply-To: <20240329072441.591471-1-samuel.holland@sifive.com>

Now that CC_FLAGS_FPU is exported and can be used anywhere in the source
tree, use it instead of duplicating the flags here.
