The SOC still has firmware baked in as per usual.

And the firmware for Bluetooth/Wifi is loaded in by having the initramfs read it from the NOR flash, mount it in /lib/firmware, then it is business as usual like a desktop Linux distribution.

It's not something special. It's just a hackjob. They shuffle the files around and made it much harder to update.
