Re: FYI: RPi* firmware tagged 1.20210805 appears to be the last to be bootable by FreeBSD via fdt use; sequence of 2 failure modes after that

[I may have also found what leads to the extra messages for
the 2nd failure mode, an independent issue it turns out.]

It looks like the extra messages, blocks of:

clk_fixed4: <Fixed clock> disabled on ofwbus0
clk_fixed4: Cannot FDT parameters.
device_attach: clk_fixed4 attach returned 6

Are tied to new dtb content in 2022's dtb updates:

        cam1_clk {
                compatible = "fixed-clock";
                #clock-cells = <0x00000000>;
                status = "disabled";
                phandle = <0x000000e2>;
        };
. . .
        cam0_clk {
                compatible = "fixed-clock";
                #clock-cells = <0x00000000>;
                status = "disabled";
                phandle = <0x000000e4>;
        };

These 2 did not exist back when the 1st failure mode
started. They appear to be repeatedly processed from
not really being handled --leading to lots of
messages.

The messages may just be noise for activity that is
not contributing to boot failures at all. So fixing
what I called the 1st failure mode might actually fix
booting for all the firmware versions after the
version tagged 1.20210805 .
