Subject: [PATCH] crypto: ccp - select CONFIG_CRYPTO_RSA
Date: Mon, 31 Jul 2017 23:10:57 +0200 [thread overview]
Message-ID: <20170731211104.2012741-1-arnd@arndb.de> (raw)
Without the base RSA code, we run into a link error:
ERROR: "rsa_parse_pub_key" [drivers/crypto/ccp/ccp-crypto.ko] undefined!
ERROR: "rsa_parse_priv_key" [drivers/crypto/ccp/ccp-crypto.ko] undefined!
Like the other drivers implementing RSA in hardware, this
can be avoided by always enabling the base support when we build
CCP.
Fixes: ceeec0afd684 ("crypto: ccp - Add support for RSA on the CCP")
