Any ideas on how to merge device tree binaries from slave devices ?

Having a PowerPC based board with various extension boards on e.g. the local bus with each board having some kind of PROM device (I2C, SPI etc.) containing a dtb ... is it possible to merge this into the existing boards dtb into the local bus node ?

Yes.

Is it already working - have I missed it ?

No - no.

If not - is someone thinking/working on it ?

We have thought about it, nobody is working on it that I am aware of.

Any suggestions on how to do it ?

See limited thoughts in http://www.denx.de/wiki/U-Boot/UBootFdtInfo

4. Proposed additional fdt commands

* merge - merge two trees. Need a conflict resolution: source tree #1 has priority? o David Gibson has talked about creating a "graft" function for libfdt.
