ppc patch queue 2018-09-25

Browse source 
Here are the accumulated ppc target patches for the last several
 weeks. Highlights are:
    * A number of 40p / PReP cleanups
    * Preliminary irq rework on the pseries machine towards the new
      XIVE interrupt controller
 
 There are a few patches which make small changes to generic device and
 arm code as prerequisites to the 40p interrupt routing cleanup.  They
 have acks from the relevant maintainers.

* remotes/dgibson/tags/ppc-for-3.1-20180925:
  40p: add fixed IRQ routing for LSI SCSI device
  lsi53c895a: add optional external IRQ via qdev
  scsi: remove unused lsi53c895a_create() and lsi53c810_create() functions
  scsi: move lsi53c8xx_create() callers to lsi53c8xx_handle_legacy_cmdline()
  scsi: add lsi53c8xx_handle_legacy_cmdline() function
  sm501: Adjust endianness of pixel value in rectangle fill
  spapr_pci: add an extra 'nr_msis' argument to spapr_populate_pci_dt
  spapr: increase the size of the IRQ number space
  spapr: introduce a spapr_irq class 'nr_msis' attribute
  40p: use OR gate to wire up raven PCI interrupts
  raven: some minor IRQ-related tidy-ups
  hw/ppc: on 40p machine, change default firmware to OpenBIOS
  target/ppc/cpu-models: Re-group the 970 CPUs together again
  Record history of ppcemb target in common.json
