[PATCH v6 0/7] PCI devices passthrough on Arm, part 2

[Oleksandr Andrushchenko <andr2000@xxxxxxxxx>]

From: Oleksandr Andrushchenko <oleksandr_andrushchenko@xxxxxxxx>

Hi, all!

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].

Thank you,
Oleksandr
