Subject: [PATCH] mmc: card: Prevent partition scan for the eMMC boot areas
Date: Wed,  3 Sep 2014 11:02:23 +0200	[thread overview]
Message-ID: <1409734943-21376-1-git-send-email-ulf.hansson@linaro.org> (raw)

It seems very unlikely that eMMC devices would hold a standard
partitiontable in one of it's boot areas. Therefore, let's prevent
them from being scanned.
