mx6slevk can run different kernel versions, such as NXP 4.1 or mainline. Currently the rootfs location is passed via mmcblk number and the problem with this approach is that the mmcblk number for the SD card changes depending on the kernel version. In order to avoid such issue, use the UUID method to specify the rootfs location. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com>
