From 84b4690f26062d000481b66d60445aea20e1da99 Mon Sep 17 00:00:00 2001 From: Fabio Berton Date: Mon, 10 Jul 2017 17:04:09 -0300 Subject: [PATCH] wandboard: Use PARTUUID to specify the rootfs location Currently the rootfs location is passed via mmcblk number and the problem with this approach is that the mmcblk number for the eMMC changes depending on the kernel version. In order to avoid such issue, use UUID method to specify the rootfs location.
