Subject: [PATCH v3 05/14] arm64: crypto: Use CC_FLAGS_FPU for NEON CFLAGS
Date: Wed, 27 Mar 2024 13:00:36 -0700 [thread overview]
Message-ID: <20240327200157.1097089-6-samuel.holland@sifive.com> (raw)
In-Reply-To: <20240327200157.1097089-1-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.
