Looks like FDT is automatic in GENERIC :

/usr/src/sys/arm64/conf/GENERIC:include		"std.broadcom"
/usr/src/sys/arm64/conf/std.broadcom:options 	FDT

Also in BROADCOM itself:

/usr/src/sys/arm64/conf/BROADCOM:include		"std.broadcom"


I've no clue for uether or axe.


The comment about "thermal@7d542000 node" seems to have an unclear status:

# grep -r @7d542000 ~/RPi5B-D0-live-newer2.dts
/root/RPi5B-D0-live-newer2.dts:		avs_monitor =
"/soc@107c000000/avs-monitor@7d542000";
/root/RPi5B-D0-live-newer2.dts:		thermal =
"/soc@107c000000/avs-monitor@7d542000/thermal";
/root/RPi5B-D0-live-newer2.dts:		avs-monitor@7d542000 {

Looking :

. . .
        soc@107c000000 {

                #address-cells = <0x1>;
                #size-cells = <0x1>;
                compatible = "simple-bus";
                phandle = <0x83>;
                ranges = <0x0 0x10 0x0 0x80000000>;
                avs-monitor@7d542000 {

                        compatible = "brcm,bcm2711-avs-monitor",
"syscon", "simple-mfd";
                        phandle = <0x9a>;
                        reg = <0x7d542000 0xf00>;
                        status = "okay";
                        thermal {

                                #thermal-sensor-cells = <0x0>;
                                compatible = "brcm,bcm2711-thermal";
                                phandle = <0x52>;
                        };
                };
. . .
