Hi @Ansuel,
Got couple NSS FW Coredumps during the system bootup today.
I've setup pstore/ramoops to capture the kernel oops/panics by reducing available memory to 460M and setup pstore/ramoops after that.
Below relevant cat /proc/iomem part:
cat /proc/iomem
root@R7800:/# cat /proc/iomem
...
42000000-5e1fffff : System RAM
42208000-42bfffff : Kernel code
42d00000-42d9bd9f : Kernel data
5e2fffff-5e304197 : ramoops:dmesg(0/9)
5e304198-5e308330 : ramoops:dmesg(1/9)
5e308331-5e30c4c9 : ramoops:dmesg(2/9)
5e30c4ca-5e310662 : ramoops:dmesg(3/9)
5e310663-5e3147fb : ramoops:dmesg(4/9)
5e3147fc-5e318994 : ramoops:dmesg(5/9)
5e318995-5e31cb2d : ramoops:dmesg(6/9)
5e31cb2e-5e320cc6 : ramoops:dmesg(7/9)
5e320cc7-5e324e5f : ramoops:dmesg(8/9)
5e324e60-5e328ff8 : ramoops:dmesg(9/9)
5e328ff9-5e329ff8 : ramoops:console
5e329ff9-5e32a7f8 : ramoops:ftrace(0/1)
5e32a7f9-5e32aff8 : ramoops:ftrace(1/1)
5e32aff9-5e32bff8 : ramoops:pmsg
Not sure whether these NSS FW core dumps are related to that pstore/ramoops setup but below are 2 separate core dumps I got today.

Edit:
These are after fresh git clone master & your nss repo merge compilation today.

Edit 2:
I would consider the above Core dumps False Positive triggered by the earlier pstore/ramoops configuration.
- Without pstore/ramoops setup I don't have issues during reboot
- With the new adjusted pstore/ramoops setup I don't have issues during reboot

For whatever reason (most likely the point where I cut the RAM availability) NSS FW was not happy and was randomly crashing either during the reboot or after some time of uptime (max 1h). Other drivers/applications did not though triggered crashes.
