Subject: [PATCH 2/3] crypto: ixp4xx - Move driver to drivers/crypto/intel/ixp4xx
Date:   Tue, 28 Mar 2023 10:39:50 -0500
Message-Id: <20230328153951.126564-3-tom.zanussi@linux.intel.com>
In-Reply-To: <20230328153951.126564-1-tom.zanussi@linux.intel.com>

With the growing number of Intel crypto drivers, it makes sense to
group them all into a single drivers/crypto/intel/ directory.

Create a separate drivers/crypto/intel/ixp4xx directory and move
drivers/crypto/ixp4xx_crypto.c to it, along with a new Kconfig and
Makefile to contain the config and make bits.

Also add a COMPILE_TEST dependency to CRYPTO_DEV_IXP4XX so it can be
more easily compile-tested.
