The Intel Quartus Prime Programming File Generator allows you to create many user partitions. These partitions can contain
application images and other items such as the Second Stage Boot Loader (SSBL), Linux* kernel, or Linux root file system.
When you create the initial flash image, you can create up to seven partitions for application images. There are no limitations
on creating empty partitions.
4.4.2.2. Sub-Partition Table Layout
The following table shows the structure of the sub-partition table. The Intel Quartus Prime software supports up to 126
partitions. Each sub-partition descriptor is 32 bytes.
