16.5.12. Booting Operation for eMMC and MMC
This section describes how to set up the controller for eMMC and MMC boot operation.
Note: The BootROM and initial software do not use the boot partitions that are in the MMC card. This means that there is no boot partition support of the SD/MMC controller.
