The series builds the PCI/MSI domain stack based on initial IORT driver which is added in first place. As a reference please see IORT spec: http://infocenter.arm.com/help/topic/com.arm.doc.den0049b/DEN0049B_IO_Remapp...
Tested on Cavium ThunderX server and Qualcomm Technologies server platform QDF2XXX. The patches can be found here: https://github.com/semihalf-nowicki-tomasz/linux.git (its-acpi-v11)
Tested-by: Eric Auger eric.auger@redhat.com on a Cavium QEMU guest with mach-virt.
Thanks
Eric
