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_Remapping_Table.pdf
Patches were built on top of accepted ARM64 ACPI PCI support and can be found
all together here:
https://github.com/semihalf-nowicki-tomasz/linux.git (its-acpi-v6)
Tested on Cavium ThunderX server.
v5 -> v6
- added locking mechanism for IORT list with domain token
- IORT function name improvements
- extended IORT RID mapping helper
- reworked IORT to be more SMMU friendly
- IORT functions which map RID and find corresponding domain are not
PCI specific any more (struct pci_dev -> struct device)
- bug fixes
v4 -> v5
- rebased against v4.7-rc1
- drop generic layer and call IORT functions directly
- improve resource abstraction and string formatting
v3 -> v4
- rebased against v4.5
- add ACPI support for IRQ domain handling on a per-device basis
- reorder domain setup step
- improve error handling
- code style improvements
v2 -> v3
- rebased on top of 4.4
- fixes and improvements for redistributor init via GICC structures
- fixes as per kbuild reports
v1 -> v2
- rebased on top of 4.4-rc4
- use pci_msi_domain_get_msi_rid for requester ID to device ID translation
