Dear John,
I would speak about XEN on ARM further.
Basically you need a passthrough in XEN terms in case you want a bus
initiator (i.e. DMA capable) device to be assigned to DomU.
For a passive device it's pretty enough to assign MMIO ranges and
interrupts using guest domain config. The pitfall here is that a device
tree generated for guest domain by xen tools will not have any assigned
device specific nodes.
But a setup with earlyprintk from one guest into the second console of a
Salvator-X board is pretty straightforward. Something more complex will
require additional hacks.

Thanks for the reply. we are using renesas rcar h3 board. Does it
supports?
XEN passthrough functionality relies on IOMMU. The R-Car Gen3 SoCs have
a custom IOMMU named IPMMU. XEN does not support IPMMU yet.
