Hi, all!

Hi Oleksandr,

This is an assorted series of patches which aim is to make some further
basis for PCI passthrough on Arm support. The series continues the work
published earlier by Arm [1] and adds new helpers and clears the way for
vPCI changes which will follow.

RFC is at [2], [3]. Design presentation can be found at [4].Hi

I have removed patch
[PATCH v6 5/7] xen/arm: do not map IRQs and memory for disabled devices
as it seems that this needs more time for decision on how to achive
that.

I have also added a new patch
[PATCH v7 4/7] xen/arm: account IO handler for emulated PCI host bridge
with a tiny latent bug fix.

This series contains all the patches which are left un-committed yet.

Thank you,
Oleksandr

As a FYI, Jan pushed today a commit that moved the headers from xen/include/asm-arm to xen/arch/arm/include/asm/.

I have handled the clash for this series while committing.

Thank you for the contribution.

Cheers,
