Subject: [PATCH v6 19/29] fpga: dfl: fme-mgr: add compat_id support
Date: Tue, 12 Jun 2018 18:10:33 +0800	[thread overview]
Message-ID: <1528798243-2029-20-git-send-email-hao.wu@intel.com> (raw)
In-Reply-To: <1528798243-2029-1-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.

Signed-off-by: Wu Hao <hao.wu@intel.com>
