Subject: [PATCH v4 1/7] xen/arm: p2m: Rename p2m_mmio_direct_nc -> p2m_mmio_direct_dev
Date: Fri, 23 Sep 2016 20:53:16 +0200 [thread overview]
Message-ID: <1474656802-24081-2-git-send-email-edgar.iglesias@gmail.com> (raw)
In-Reply-To: <1474656802-24081-1-git-send-email-edgar.iglesias@gmail.com>
From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>
Rename p2m_mmio_direct_nc to p2m_mmio_direct_dev to better
express that we are mapping device memory. This will allow us
to use p2m_mmio_direct_nc for Normal Non-Cached mappings.
No functional change.
