# The output of the u-boot build process is u-boot.bin.  Older firmware
# versions require a standard header, but the recent versions (our case)
# are capable of booting u-boot.bin directly.  Also copy the entire
# contents of the bootfiles distribution (these are proprietary binary
# files required to boot).
# Also include the armstub8.bin needed to go SMP on RPI3
