I don't know what NXID and CCID is, but have you seen Wolfram's proposal
for sub-devicetrees?
http://ozlabs.org/pipermail/linuxppc-dev/2008-June/058263.html
Our aim here is to put device tree sniplets into eeproms or flash areas;
we have several boards here that consist of
- a module
- a base board
- maybe an extension board
and having sub devicetrees would make it possible to simply put the
devicetree for each component into a piece of storage *on the
component*. So the bootloader and later Linux would be able to build the
whole tree from these sniplets.
