Quoting from https://www.openbsd.org/78.html :

    • Added support for Raspberry Pi 5 (with console on serial port).
. . .
    • Make the cad(4) Ethernet interface on the Raspberry Pi 5 work by configuring the delays for RGMII PHYs correctly.

Also, quoting https://man.openbsd.org/bcmstbpinctrl.4 :

"The bcmstbpinctrl driver uses pin control data from the device tree to select one of multiple possible roles available for pins on Broadcom Set-top Box SoCs. This includes the Broadcom BCM2712 SoC that is used in the Raspberry Pi 5. It does not provide direct device driver entry points but makes its functions available to other drivers."

So: Device Tree, not ACPI, for that.

There are no special instructions about using UEFI/ACPI . I expect it is
U-Boot based by default and works with their miniroot78.img without
substitutions for such.
