From b6e2a3747e3cffdf3cc515b0ce35d6bcdcb051c5 Mon Sep 17 00:00:00 2001
From: Cristian Stoica <cristian.stoica@freescale.com>
Date: Tue, 9 Dec 2014 16:41:25 +0200
Subject: [PATCH] don't advertise RSA keygen
This is supposed to avoid RSA keygen operations when they are not
available. Since no testing can be done, the patch should be applied
selectively (for example when offloading through pkc driver on C293)
