Subject: [net-next 2/6] e1000e: remove calls to ioremap/unmap for NVM addr
Date: Fri,  6 Mar 2015 03:06:02 -0800	[thread overview]
Message-ID: <1425639966-6829-3-git-send-email-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <1425639966-6829-1-git-send-email-jeffrey.t.kirsher@intel.com>

From: Yanir Lubetkin <yanirx.lubetkin@intel.com>

Starting I219, the NVM will not be mapped to its own BAR, but to an
address region in another bar.  The mapping/unmapping is relevant
to older HW only.
