It's hard to give a time estimate for such work because this
really depends so much on the experience and calibre of the
people doing the work. That said, porting eCos to a new
machine architecture is non-trivial and can take someone with
experience with eCos anywhere from 4-12 weeks (I've done a
number of these and those are representative costs).
Note: I'm not trying to make this sound like a huge task,
rather that there are lots of details to consider and get
correct and it simply takes time, often more than one might
wish.
