Subject: [PATCH v5 19/28] fpga: dfl: fme-mgr: add compat_id support
Date: Wed,  2 May 2018 10:50:22 +0800	[thread overview]
Message-ID: <1525229431-3087-20-git-send-email-hao.wu@intel.com> (raw)
In-Reply-To: <1525229431-3087-1-git-send-email-hao.wu@intel.com>

This patch adds compat_id support to fme manager driver, it
reads the ID from the hardware register. And it could be used
for compatibility check before partial reconfiguration.
