From b8fbdc2bc4e71b62646031d5df5f08aafe15d5ad Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Tue, 21 May 2019 13:34:09 +0000 Subject: [PATCH] crypto: talitos - reduce max key size for SEC1 SEC1 doesn't support SHA384/512, so it doesn't require longer keys. This patch reduces the max key size when the driver is built for SEC1 only.
