Here's one other requirement I'd like that I don't think I saw
explicitly mentioned in your document:
Assuming a base file board.dts and a child board file child.dts, the
compiled file child.dtb should be usable with a modified board.dtb
assuming it exports the same set of attachment-points (hashed phandles,
socket objects, whatever). This allows bug-fixes etc. to board.dts
without forcing every child.dts to be recompiled.
If the attachment points is hashed node names or node content from
board.dts, I'm not sure how this is possible?
I suppose this is implicit if child.dtb can be used with either
board-a.dtb and board-b.dtb though.
