mips_fulong2e: do not use isa_mmio

This board is little-endian, but still isa_mmio should die. :)

pci: Replace pci_find_domain() with more general pci_root_bus_path()

pci_find_domain() is used in a number of places where we want an id for a
whole PCI domain (i.e. the subtree under a PCI root bus). The trouble is
that many platforms may support multiple independent host bridges with no...

q35: set fw_name

PCI host bridges need to set fw_name to be discoverable
by bios for boot device selection.

In particular, seabios expects root device to be called
"/pci/@i0cf8", so let's set it up like that for Q35.

Revert "versatile_pci: Put the host bridge PCI device at slot 29"

This reverts commit 5f37ef92b7690423ac6311d3c597e182fc5f8fe6.
It turns out that some kernels incorrectly depend on the
old QEMU behaviour of not putting the host PCI bridge device
where the hardware puts it, because they use a swizzling IRQ...

hw/pci-host/versatile.c: Update autodetect to detect newer kernels

Newer versatilepb kernels still don't get the IRQ mapping right
for the PCI controller, but they get it differently wrong (they add
a fixed +64 offset to everything they write to PCI_INTERRUPT_LINE)....

sparc64: use direct interrupt mapping for PCI devices

Every PCI Slot in PBM has 4 directly mapped IRQ lines.

described in Section 19.3.3 of UltraSPARC™-IIi User's Manual.

Please note that this patch requires the OpenBIOS counterpart patch....

hw/versatile_pci: Drop unnecessary vpb_pci_config_addr()

Drop the vpb_pci_config_addr() function -- it is unnecessary since
the size of the memory regions means the hwaddr is always within
the 24 bit size. (This function was probably a leftover from when...
