Whither boot programs

[M. Warner Losh]

There's a bunch of AT91 boot programs that I have committed.  These
are all AT91 specific, although I'm sure someone could tease out the
more generally useful bits (like SD/MMC or xmodem goo).  For the
moment, I've disabled installing them because they were winding up in
/, which is clearly wrong.

What's the best way to install these?

(a) Never install or build
(b) Only install when the specific sub-port is built (might be hard
    since buildworld has no knowledge of the sub-port).
(c) Install them into /boot/at91_foo?
(d) Install them into /boot/at91/foo?

I'm leaning towards (a) or (c) (c more heavily).
