[Qemu-ppc] [PATCH v8 0/3] spapr_pci: PCI DT node creation in QEMU

[Nikunj A Dadhania]

The patch series creates PCI device tree(DT) nodes in QEMU. The new
hotplug code needs the device node creation in QEMU. While during
boot, nodes were created in SLOF. It makes more sense to consolidate
the code to one place for better maintainability.

New slof.bin is already there in spapr-next

Changelog V7:
* Rebased to spapr-next
* Dropped three patches that have been picked upstream
* Limited usage of sPAPRFDT to pci enumeration code (David Gibson)
* Reworked all the patches and moved cleanup in last patch.

Changelog V6:
* Open coded fdt_setprop_string as the return would 
  leak memory (Thomas Huth)

Changelog V5:
* Reworked enumerate bridges to reduce scopes (Alexey)
* Fixed unit address which should be hex
* Added FDT_NAME_MAX and use snprintf for composing name (Alexey)
* Added patch to drop redundant args and change prototype (Alexey)
* Added bus number in the ibm,loc-code for qemu emulated or failed
  vfio device. 
* Now qemu_<name>:<phb-index>:<bus>:<slot>.<fn> is having
  hex encoding (Alexey)

Changelog V4:
* Refactored and simplified the "ibm,loc-code" patch

Changelog V3:
* Dropped duplicate macro patches
* Squashed Michael's drc_index changes to enumeration patch
* Use common create routine for boottime and hotplug case
* Proper error handling not depending on g_assert
* Encode vfio loc-code if getting loc-code from host fails

Changelog V2:
 * Fix device tree for 64-bit encoding
 * Fix the class code, was failing xhci
 * Remove macro duplication
 * Fix DT fields generation for boot time device (Michael Roth)

Changelog v1:
 * Correct indent problems reported by checkpatch(David Gibson)
 * Declare sPAPRFDT structure as local (David Gibson)
 * Re-arrange code to avoid multiple indentation (Alexey Kardashevskiy)


Nikunj A Dadhania (3):
  spapr_pci: enumerate and add PCI device tree
  spapr_pci: populate ibm,loc-code
  spapr_pci: drop redundant args in spapr_[populate,create]_pci_child_dt
