Subject: [RFC PATCH 08/20] crypto: cesa/aes - switch to library version of key expansion routine
Date: Wed, 12 Jun 2019 14:48:26 +0200	[thread overview]
Message-ID: <20190612124838.2492-9-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20190612124838.2492-1-ard.biesheuvel@linaro.org>

Switch to the new AES library that also provides an implementation of
the AES key expansion routine. This removes the dependency on the
generic AES cipher, allowing it to be omitted entirely in the future.
