The following example shows the detailed manner in which you can write a BIF while grouping the partitions together. Versal adaptive SoC now uses the updated BIF syntax to support subsystems. You can combine multiple partitions to form one image, called a subsystem, that shares a single image header.
Note: Partitions under the same image { } block
merge to form a single subsystem.

id_code = 0x04ca8093
extended_id_code = 0x01
