STM32 Firewall bus for v6.19, round 1
Highlights:
----------
The STM32MP21x platforms have a slightly different RIFSC. Add support
for these platforms.
Also, the RIF is a complex firewall framework which can be tricky
to debug. To facilitate the latter, add a debugfs entry that can
be used to display the whole RIFSC firewall configuration at runtime.
