Each 32-byte sub-partition descriptor contains the following information:
Table 48. Sub-partition Descriptor Layout
Offset Size Description
0x00
16 Sub-partition name, including a null string terminator
0x10
8 Sub-partition start offset
0x18
4 Sub-partition length
0x1C
4 Sub-partition flags
Two flags are currently defined:
System set to 1: Reserved for RSU system. For partition offset value, refer to Table 46 on page 175.
Read only set to 1: The system protects partition against direct writes.
The Intel Quartus Programming File Generator sets these flags as follows at image creation time, then they are not changed
afterward:

Note: In order to successfully update SPTs, the HPS software (U-Boot or Linux) must be configured to have a QSPI erase granularity
of 32 KB or less. When configured with a coarser erase granularity (like 64 KB for example), the operation fails. All supported
flash devices offer erase granularities of 4 KB, 32 KB, and 64 KB, and the default for the current HPS software is 4 KB.
