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 ?
