Something I lamented in another thread is that we need to move things to
include/environment/ so that they can be re-used easily. Lets start by
putting the "distro boot" SF stuff in to include/environment/distro/sf.h
and #include that here. That way anything else that really does have
something written to SPI flash in this manner can opt-in without
duplication of the logic.
Thanks!
