RPI5 16GB panic on boot

Hi,

All my goodies are in and connected so I could capture the logs via serial easily.

The RPI5 16GB starts booting the kernel and then panics very early in the process.

The full serial output can be found here: https://wiki.freebsd.org/RonaldKlop/Raspberry%20Pi%205%2016GB.

The TL;DR is:
Hit [Enter] to boot immediately, or any other key for command prompt.
Booting [/boot/kernel/kernel]...               
Loading splash ok
No valid device tree blob found!
WARNING! Trying to fire up the kernel, but no device tree blob found!

Any thoughts about what I could try to fix this?
