STM32H5 Flash layout obk and sytem

Is there a comprehensive single documentation source of the Flash layout for say, an STM32H563?

The documentation I find is very opaque.  Questions I have at present (From a non secure perspective):
1. Where is OBK located? (0x0BF0000 to 0x0BF9FFFF ???)

2. Where is system located?

3. Is RSSLIB actually using OBK memory? Or is this located somewhere else?

4. Is there a way to self program the debug password for PRODUCT_STATE > OPEN?

5. If #5 true, are there some real docs on this?  All I find so far is tutorials and code for the 573 in a secure perspective.

Hmm.  I wonder if this is even an option in a NS application.

 

unsigned char * obk = (unsigned char *)FLASH_OBK_HDPL3NS_BASE_NS;

 

Basically all I can read is 0x00's , so there must be some undefined issue.  HDPL is 0 as far as I can tell.

 

Ultimately the doc's are geared toward the 573 and or TZ enabled.
