Bingo.  Jeez, I must have porridge for brains.

     augur2:/u0/crochet # find [b-o]* -type f | xargs grep -w bootcode.bin
     [...]
     board/RaspberryPi2/setup.sh:    cp ${UBOOT_PATH}/bootcode.bin .

So a look shows that a raspberry_pi_populate_boot_partition()
is doing a long stick of unconditionalized copys from ${UBOOT_PATH}
into . , which must be the FAT boot partition (didn't bother to check.)

I replaced the cp's with

     # Copy RaspberryPi 2 boot files to FAT partition
     #
     for f in LICENCE.broadcom README bootcode.bin config.txt fixup.dat fixup_cd.dat \
              fixup_x.dat start.elf start_cd.elf start_x.elf u-boot.bin ; do
         if [ -f ${UBOOT_PATH}/$f ] ; then
             cp ${UBOOT_PATH}/$f .
             echo :rwa: copied ${UBOOT_PATH}/$f
         else
             echo :rwa: no ${UBOOT_PATH}/$f
         fi
     done

I've kicked it off, film at 11.

regards,
Ross
