Hi Ronald,

even u-boot is actively working on ACPI-int= egration and of course 
on bcm2712-support.
=
So u-boot is not a dead project like that WindowsOnArm and I= think 
tracking the upstreams(u-boot,Linux& R= PILinux/Firmwares) is the way to go if don`t want to wait =E2=80=9E100 years= =E2=80=9C again to get a useful RPI-support.
But even u= -boot`s latest integrations of e.g. reasonable compat-strings are quite = ;
new( 5 days or so).. so what we can say for sure:
Yes, bootlaoder-support will come but if we do not want t= o stay months or even years behind , there`s something to do, specially(patc= hed) bootloader-integration/updates 
and the corr= esponding driver-patches, mainly pcie&genet..

=
As the logs I`ve sent say, I`m currently trying to mo= unt root :-) ,
after reaching that state I can make my= currently private repos public for collaboration,
tha= nks for your interest in helping FreeBSD with RPI-support.
As a starting point I would recommend trackingv the upstreams, understa= nding 
the u-boot file-structure and reading(real= ly hard to understand;-) e.g. the pcie drivers.  

thanks
Regards
Klaus

=EF=BB=BFHi Klaus,

I was under the impression that the pre-16GB RPI5 were booting using ACPI de= vice enumeration. (https://wiki.freebsd.org/arm/Raspberry%20Pi%205) That is why I hoped t= he 16GB version to work similarly.
I don't have a personal preference for one way or the other (ACPI vs DTB).
Is your work available in a public repository somewhere? So I could try and s= ee if I can help somehow.

Regards,
Ronald.

For FreeBSD go the u-boot fdt-based way ! ( since all existing drivers rely o= n that)..
A device tree blob( dtb) is a compiled binary which is read in by u-boot , While a device tree source( dts) can be compiled into u-boot`kernel directly= =E2=80=A6.

Some steps further here. I just show you the things I=E2=80=99ve already hac= ked ( in u-boot & fbsd-kernel),
Not showing you the things which have to be future-hacked into the kernel:-)= ,
 it=E2=80=99ll be a massive hack because e.g because the RP1 chip has m= any things  hanging behind pcie,
I have currently  pcie detected in boot but there`s something more to d= o/hack regarding DMA=E2=80=A6.. and so further and so on   :
