Subject: [PATCH 1/2] firmware: Intel: Add Stratix10 ECC DBE SMC call
Date:   Fri, 29 Mar 2019 09:43:58 -0500
Message-Id: <1553870639-23895-1-git-send-email-thor.thayer@linux.intel.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Thor Thayer <thor.thayer@linux.intel.com>

Reserve ECC Double Bit Error SMC call to alert U-Boot that
a DBE has occurred. Moving the call from local EDAC header
file to this common file.
