- * Input Parameters:
- * ack: 0x0 - No boot acknowledge sent (default)
- *	0x1 - Boot acknowledge sent during boot operation
- * part_num: User selects boot data that will be sent to master
- *	0x0 - Device not boot enabled (default)
- *	0x1 - Boot partition 1 enabled for boot
- *	0x2 - Boot partition 2 enabled for boot
- * access: User selects partitions to access
- *	0x0 : No access to boot partition (default)
- *	0x1 : R/W boot partition 1
- *	0x2 : R/W boot partition 2
- *	0x3 : R/W Replay Protected Memory Block (RPMB)
