1. You cannot "simply start and complete the addition with a new 
header". That is only the fourth step that I described above.
2. You have to do *all* the steps I mentioned in order to have support 
for the new device in the compiler.
3. I said that all of those steps can be done in *any order*.
4. The conversation that you quoted earlier in the thread had actually 
not much to do with supporting the new devices. So you may or may not be 
misinformed as to what is going on.
