On ARM we can passthrough 2 different types of device: PCI device and
platform device described in the device tree (it's a tree representation
of the hardware).
Sure, dts is always popular in most embedded systems, and actually I
really like that ;-)
This assign_device callback deals with the latter. So from the name the
value doesn't look right.
What about XEN_DOMCTL_DEV_RDM_XXX?
Thanks
