One of the goals of the new tool was to bring everything up to the top 
level. People were getting lost in the maze of include files and option 
settings. The disadvantage, as you point out, is some duplicated code, but 
the advantages have so far outweighed that disadvantage. 

In this case duplicated code is actually not too bad, as the hardware that 
the code describes will not change for a given board.

Ah, this is a chain and not a true parent/child case? I'm still getting 
the hang of HT, obviously.
