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:

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:

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
