What does FreeBSD do with "Both"? Does it actually use some ACPI
and some Device Tree? Or does it just use ACPI? Does your
combination do anything different than just using ACPI?

Sounds like the same status as booting just ACPI with no such
adjustments too bcm2835bcm2835_vcbus.c or sdhci_fdt.c ?

I think Mike Karels plans on investigating getting Ethernet
going based on cgem . I've no clue if this is ACPI, DeviceTree,
or both.

My usage has been pure ACPI, no software adjustments specific
to getting the RPi5 operational. Use of a USB3 Ethernet dongle.
