dec.c - move to pci-bridge

Looks like dec.c is in pci-host by mistake.
Moving it over to pci-bridge.

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)....

hw/pci-host/versatile.c: Provide property for forcing broken IRQ mapping

Although we try our best to automatically detect broken versions
of Linux which assume the old broken IRQ mapping we used to implement
for our model of the Versatile PCI controller, it turns out that...

sparc64: use direct interrupt mapping for PCI devices

Every PCI Slot in PBM has 4 directly mapped IRQ lines.
Use the IRQ routing schema 0bssnn (Bus, Slot, interrupt Number)
described in Section 19.3.3 of UltraSPARC™-IIi User's Manual.

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

sparc64: fix loosing interrupts

- clear interrupts only on writing to the interrupt clear registers
- don't overwrite a currently active interrupt request
- use the correct addresses for the interrupt clear registers
(section 19.3.3.3 of the UltraSPARC™-IIi User’s Manual)...

sparc64: allow 64 IRQ lines

According to UltraSPARC™-IIi User’s Manual, PBM has 64 IRQ lines.

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...

versatile_pci: Expose PCI memory space to system

The VersatilePB's PCI controller exposes the PCI memory space to the
system via three regions controlled by the mapping control registers.
Implement this so that guests can actually use MMIO-BAR PCI cards....
