Using an SD card or an eMMC device assumes that <code>bootfile</code>, <code>fdt_file</code> and <code>splashfile</code> are stored into fist MMC device partition.  Then, u-boot uses the previously listed commands for reading the binary images and starting the Linux bootstrap file system from the eMMC ''MMC part 2'' (which is reserved for the root-file system storage):
