Oh, nice catch.  I've twisted up a copy of sysutils/rpi-firmware.
Copying that stuff into what crochet built on da0s1 got me to a boot
prompt, as thus:

     U-Boot 2017.09 (Dec 26 2017 - 11:11:20 -0700)

This can't be good ...

     Number of U-Boot devices: 1

     Found U-Boot device: disk

       Checking unit=0 slice=<auto> partition=<auto>... good.
     Booting from disk0:

     can't load 'kernel'

     Type '?' for a list of commands, 'help' for more detailed help.
     loader>

which is great, now all I have to do is remember the syntax for
the boot path.  lsdev shows

     loader> lsdev
     disk devices:
            disk0 (MMC)
            disk0s1: DOS/Windows
            disk0s2: FreeBSD
            disk0s2a: FreeBSD UFS
     net devices:
            net0:

A naive "boot -s disk02a:/boot/kernel/kernel" doesn't work, and
ls isn't implemented.  Nothing I can think of is a good path.
Mounting the mmscd on the devel box shows:

     augur2:/root # mount -o ro /dev/da0s2a /mnt0
     augur2:/root # ls -l /mnt0/boot/kernel/kernel
     -r-xr-xr-x  1 root  wheel  10649356 Dec 29 02:27 /mnt0/boot/kernel/kernel

     augur2:/root # file /mnt0/boot/kernel/kernel
     /mnt0/boot/kernel/kernel: ELF 32-bit LSB executable, ARM, EABI5 version 1 \
     (FreeBSD), dynamically linked, interpreter /red/herring, for FreeBSD 12.0 \
     (1200054), not stripped

Anyway I'm downloading an image from ftp.freebsd.org and will see
what I can learn from inspecting it.  I'm surprised that crochet
has lost track of the pi2, though.  Lots of them still out there.

regards,
Ross
