You CCed this to 
b21284@freescale.com.  Who is that?  It would be nice to use "friendly" 
e-mail addresses, but at least include the name along with the e-mail address.

I suggest CCing the people who added these device trees.

If you mean that the physical address of the memory region is <= 0xbfff_ffff, 
I don't see the relevance.

By "boundary" do you mean the PCIe bus address?  Why is it a problem for 
these independent PCIe root complexes to have the same PCIe bus addresses?

What is illicit about it?

Why isn't the problem seen in the 36-bit device trees, which do the same 
thing?
