This is the only explanation for the patch. It does not explain the name
ROM_UNIFIED_SECTION and what it has to do with  HAB_RVT_BASE.
I agree that users must read the manual, but even a better and longer
description in the commit message helps.

This is not ok. We are in the process to move all CONFIG_ from the board
configuration file to Kconfig. New CONFIG_ should be added only via Kconfig.

As ROM_UNIFIED_SECTIONS is like a property for the SOC, the selection of
the SOC type must add automatically it to the config. You can see as
example SYS_L2CACHE_OFF for i.mx6ul.

Best regards,
Stefano Babic
