| eMMC boot partition use |
| ======================= |
| |
| It is possible, depending on SYSBOOT configuration to boot from the eMMC |
| boot partitions using (name depending on documentation referenced) |
| Alternative Boot operation mode or Boot Sequence Option 1/2. In this |
| example we load MLO and u-boot.img from the build into DDR and then use |
| 'mmc bootbus' to set the required rate (see TRM) and 'mmc partconfig' to |
| set boot0 as the boot device. |
