Re: you`ll have to hack u-boot&kernel drivers Re: RPI5 16GB panic on boot

Hi Klaus,

I was under the impression that the pre-16GB RPI5 were booting using ACPI device enumeration. (https://wiki.freebsd.org/arm/Raspberry%20Pi%205) That is why I hoped the 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 see if I can help somehow.

Regards,
Ronald.
