Subject: [PATCH 03/15] crypto: arm64 - remove CRYPTO dependency of library functions
Date: Thu, 17 Apr 2025 11:26:11 -0700	[thread overview]
Message-ID: <20250417182623.67808-4-ebiggers@kernel.org> (raw)
In-Reply-To: <20250417182623.67808-1-ebiggers@kernel.org>

From: Eric Biggers <ebiggers@google.com>

Continue disentangling the crypto library functions from the generic
crypto infrastructure by removing the unnecessary CRYPTO dependency of
CRYPTO_CHACHA20_NEON and CRYPTO_POLY1305_NEON.  To do this, make
arch/arm64/crypto/Kconfig be sourced regardless of CRYPTO, and
explicitly list the CRYPTO dependency in the symbols that do need it.
