Subject: [U-Boot] [PATCH 1/3] armv8/mmu: Clean up TCR programming
Date: Thu, 20 Aug 2015 11:52:13 +0200 [thread overview]
Message-ID: <1440064335-25909-1-git-send-email-thierry.reding@gmail.com> (raw)
From: Thierry Reding <treding@nvidia.com>
Use the inner shareable attribute for memory, which makes more sense
considering that this code is called when caches are being enabled.
