[Qemu-ppc] [PATCH 0/2] sam460ex: Improve logicial or'ed PCI-X interrupts

Subject: [Qemu-ppc] [PATCH 0/2] sam460ex: Improve logicial or'ed PCI-X interrupts
Date: Tue, 31 Jul 2018 06:36:33 +0200

The previous change 70a8ff3fd0c27e69a598e7603112de9d0fec5380 fixed
the interrupt connection not properly as the IRQ levels would not
be logcical or'ed. While other PCI cards already have worked with
that change, it didn't model the expected hardware behaviour
close enough.

This patch series is an attempt to fix this remaining problem.
Firtsly, it introduces the num-irqs property to the pci-xbus class
and implements the one common IRQ as a special case. The PCI bus
implementation logic will handle the logical or for us then.

Secondly, it adjust the sam460ex code to take advantage of the
new property.

Tested on the SAM460ex machine (which admittely is the only user
so far).

  sam460ex: Create the PCI-X bus with only one interrupt
