When investigating FDTs for creation of machine I found it's easy to invent something that can handle the simple integrator/cp board, but it all starts to fall apart when you encounter more complicated boards. In particular things like PCI, USB, I2C, etc. and strange bus configurations when you have both on-chip and external devices. Paul
