Subject[PATCH v1 03/15] crypto: talitos - reduce max key size for SEC1
Date
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.

Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
Fixes: 03d2c5114c95 ("crypto: talitos - Extend max key length for SHA384/512-HMAC and AEAD")
