[U-Boot] dtb merge

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 ?

Is it already working - have I missed it ?

If not - is someone thinking/working on it ?

Any suggestions on how to do it ?

Regards,

Andre
