Subject: [U-Boot] [PATCH v2 3/5] colibri_vf: use UUID for rootfs
Date: Wed, 29 May 2019 13:00:41 +0300	[thread overview]
Message-ID: <20190529100043.14802-3-igor.opaniuk@gmail.com> (raw)
In-Reply-To: <20190529100043.14802-1-igor.opaniuk@gmail.com>

From: Igor Opaniuk <igor.opaniuk@toradex.com>

Replace usage of "/dev/mmcblk*p*" with a proper UUID of rootfs
partition. This fixes the issue, when MMC controllers are probed in
a different order in U-boot and Linux kernel.
