Hi list,
I am very new to device trees and have some questions. I am working on an
embedded x86 device, which has some extra chips connected to an i2c bus.
As it is not possible to probe for these devices - no ID register etc
- I am looking
into DT/FDT.
How is it possible to pass the FDT to the linux kernel via grub? How far is FDT
support for x86?
Thanks

I don't think any work has been done to pass DT using grub. Right now
(IIRC) the DT is passed via the x86 boot protocol
(Documentation/x86/boot.txt), but I don't see the device tree bits in
the current mainline version of that document.
