Commit: 0858eccf86e9b3611d711717ec65a042f5c7ff9f
From: Artur Paszkiewicz <artur.paszkiewicz@intel.com>
Date: Wed, 19 Nov 2014 13:53:29 +0100
Subject: [PATCH 4/5] imsm: detail-platform improvements
References: FATE#318193

Print platform details per OROM, not per controller, differentiate
RST(e) platforms from legacy IMSM, print NVMe device paths, adjust port
printing to newer sysfs path.
