Those flags are mentioned directly in the innovator CDL - they probably
should not be.

Also note: the comment in 'ecos.db' says that this platform is not fully
eCos-ready, only RedBoot is supported, so I'm not sure what success you
will have overall.  (n.b. I've not tried this platform at all, so the
comments may be out of date w.r.t. the actual port)
