Subject: [PATCHv3 4/9] EDAC, altera: Abstract ECC Enable Mask in check_deps()
Date: Mon, 21 Mar 2016 11:01:41 -0500 [thread overview]
Message-ID: <1458576106-24505-5-git-send-email-tthayer@opensource.altera.com> (raw)
In-Reply-To: <1458576106-24505-1-git-send-email-tthayer@opensource.altera.com>
From: Thor Thayer <tthayer@opensource.altera.com>
In preparation for the Arria10 peripheral ECCs, the
ECC Enable mask is used in place of hard coded masks
in the check dependency functions.
