Subject: [PATCH 04/14] crypto: inside-secure - filter out the algorithms by engine
Date: Thu, 28 Jun 2018 17:15:34 +0200 [thread overview]
Message-ID: <20180628151544.22134-5-antoine.tenart@bootlin.com> (raw)
In-Reply-To: <20180628151544.22134-1-antoine.tenart@bootlin.com>
EIP engines do not support the same set of algorithms. So far the
supported engines in the Inside Secure SafeXcel driver support the same
set of algorithms, but that won't be true for all engines. This patch
adds an 'engines' field in the algorithm definitions so that they only
are registered when using a compatible cryptographic engine.
