Thank you!  This is wonderful!
I've merged this to the code on Github.

I only have one suggestion for improving it:

You use this code to get the kernel object file:

 KERNELBIN=3D${WORKDIR}/obj/arm.armv6`realpath =
${FREEBSD_SRC}`/sys/${KERNCONF}/kernel.bin

then

   dd of=3D$FLASH =1B$B!D=1B(B. if=3D$KERNELBIN

This approach is a little brittle.   Elsewhere,
I've used something similar to the following:

   mkdir ${WORKDIR}/kernel
   freebsd_kernel_install ${WORKDIR}/kernel
   dd .... if=3D${WORKDIR}/kernel/.../kernel.bin

If this doesn't work, please consider adding a new
function to lib/freebsd.sh to copy kernel.bin; that way,
there will be only one place that knows about this
kind of detail.  (Rather than having copies of your
code for every board.)
