Subject: [PATCH 3/7] arm: mach-omap: Change mountpoint of boot partitions
Date: Fri, 28 Apr 2017 14:46:04 +0200	[thread overview]
Message-ID: <1493383568-27798-3-git-send-email-d.schultz@phytec.de> (raw)
In-Reply-To: <1493383568-27798-1-git-send-email-d.schultz@phytec.de>

If using EMMC and SD as bootsources, mounting the boot partition of both
devices to /boot makes trouble. Either the correct device is mounted to
/boot or a remount of /boot has to be performed.

To ensure this problem each MMCn bootsource will be mounted to his own
path in /mnt/{mmc,emmc}.
