d0f4aa7d50 target/hppa qemu v8.2 regression fixes
There were some regressions introduced with Qemu v8.2 on the hppa/hppa64
 target, e.g.:
 
 - 32-bit HP-UX crashes on B160L (32-bit) machine
 - NetBSD boot failure due to power button in page zero
 - NetBSD FPU detection failure
 - OpenBSD 7.4 boot failure
 
 This patch series fixes those known regressions and additionally:
 
 - allows usage of the max. 3840MB of memory (instead of 3GB),
 - adds support for the qemu --nodefaults option (to debug other devices)
 
 This patch set will not fix those known (non-regression) bugs:
 - HP-UX and NetBSD still fail to boot on the new 64-bit C3700 machine
 - Linux kernel will still fail to boot on C3700 as long as kernel modules are used.
 
 Changes v2->v3:
 - Added comment about Figures H-10 and H-11 in the parisc2.0 spec
   in patch which calculate PDC address translation if PSW.W=0
 - Introduce and use hppa_set_ior_and_isr()
 - Use drive_get_max_bus(IF_SCSI), nd_table[] and serial_hd() to check
   if default devices should be created
 - Added Tested-by and Reviewed-by tags
 
 Changes v1->v2:
 - fix OpenBSD boot with SeaBIOS v15 instead of v14
 - commit message enhancements suggested by BALATON Zoltan
 - use uint64_t for ram_max in patch #1

3b57c15f02 hw/pci-host/astro: Add missing astro & elroy registers for NetBSD
NetBSD accesses some astro and elroy registers which aren't accessed
by Linux yet. Add emulation for those registers to allow NetBSD to
boot further.
Please note that this patch is not sufficient to completely boot up
NetBSD on the 64-bit C3700 machine yet.

64bf09674a hw/pci-host/astro: Trigger CPU irq on CPU HPA in high memory
The CPU HPA is in the high F-region on PA2.0 CPUs, so use F_EXTEND()
to trigger interrupt request at the right CPU HPA address.
Note that the cpu_hpa value comes out of the IRT, which doesn't store the
higher addresss bits.

ba7d12eb8c hw/pci: modify pci_setup_iommu() to set PCIIOMMUOps
This patch modifies pci_setup_iommu() to set PCIIOMMUOps
instead of setting PCIIOMMUFunc. PCIIOMMUFunc is used to
get an address space for a PCI device in vendor specific
way. The PCIIOMMUOps still offers this functionality. But
using PCIIOMMUOps leaves space to add more iommu related
vendor specific operations.
