Hello to everyone.

I ported the panfrost driver on FreeBSD 15.0 for my radxa zero 3W board. I
mean,I've been able to fix all the errors I found and I compiled correctly
the kernel and the modules. Unfortunately,when I tried to boot it,this is
what happened :

It is stuck there. My sensation is that the problem can be fixed easily.
But I need to understand why. What could be the reason,what to try and so
on.

Anyway,I want to share the source code of the kernel ,the compiled kernel
and the modules,if someone wants to study the code and try on his board :
