=======================

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.
