c451e07798 hw/mips/Kconfig: Track Malta's PIIX dependencies via Kconfig
Tracking dependencies via Kconfig seems much cleaner.

Note that PIIX4 already depends on ACPI_PIIX4.

3c73d590e7 hw/isa/piix4: Decouple INTx-to-LNKx routing which is board-specific
pci_map_irq_fn's in general seem to be board-specific, and PIIX4's
pci_slot_get_pirq() in particular seems very Malta-specific. So move the
latter to malta.c to 1/ keep the board logic in one place and 2/ avoid
PIIX4 to make assumptions about its board.

f021f4e9d2 hw/pci/pci: Factor out pci_bus_map_irqs() from pci_bus_irqs()
pci_bus_irqs() coupled together the assignment of pci_set_irq_fn and
pci_map_irq_fn to a PCI bus. This coupling gets in the way when the
pci_map_irq_fn is board-specific while the pci_set_irq_fn is device-
specific.

For example, both of QEMU's PIIX south bridge models have different
pci_map_irq_fn implementations which are board-specific rather than
device-specific. These implementations should therefore reside in board
code. The pci_set_irq_fn's, however, should stay in the device models
because they access memory internal to the model.

Factoring out pci_bus_map_irqs() from pci_bus_irqs() allows the
assignments to be decoupled, resolving the problem described above.

Note also how pci_vpb_realize() which gets touched in this commit
assigns different pci_map_irq_fn's depending on the board.

08899b5c68 target/arm: allow writes to SCR_EL3.HXEn bit when FEAT_HCX is enabled
ARM trusted firmware, when built with FEAT_HCX support, sets SCR_EL3.HXEn bit
to allow EL2 to modify HCRX_EL2 register without trapping it in EL3. Qemu
uses a valid mask to clear unsupported SCR_EL3 bits when emulating SCR_EL3
write, and that mask doesn't include SCR_EL3.HXEn bit even if FEAT_HCX is
enabled and exposed to the guest. As a result EL3 writes of that bit are
ignored.

1953dfa80e hw/mips/malta: Set PIIX4 IRQ routes in embedded bootloader
Linux kernel expects the northbridge & southbridge chipsets
configured by the BIOS firmware. We emulate that by writing
a tiny bootloader code in write_bootloader().

Upon introduction in commit 5c2b87e34d ("PIIX4 support"),
the PIIX4 configuration space included values specific to
the Malta board.

Set the Malta-specific IRQ routing values in the embedded
bootloader, so the next commit can remove the Malta specific
bits from the PIIX4 PCI-ISA bridge and make it generic
(matching the real hardware).

YAMON does some endian-swapped acceses on the ISD<->PCI CFG/DATA
registers. These tests are useful to debug cross-endianness issues,
in particular on big-endian host.

145e2198d7 hw/mips/gt64xxx_pci: Endian-swap using PCI_HOST_BRIDGE MemoryRegionOps
GT64120's PCI endianness swapping works on little-endian hosts,
but doesn't on big-endian ones. Instead of complicating how
CFGADDR/CFGDATA registers deal with endianness, use the existing
MemoryRegionOps from hw/pci/pci_host.c. Doing so also reduce the
access to internal PCI_HOST_BRIDGE fields.

Map the PCI_HOST_BRIDGE MemoryRegionOps into the corresponding
CFGADDR/CFGDATA regions in the ISD MMIO and remove the unused
code in the current ISD read/write handlers.

Update the mapping when PCI0_CMD register is accessed (in case
the endianness is changed).

This allows using the GT64120 on a big-endian host (and boot
the MIPS Malta machine in little-endian).

9f81e43f10 hw/mips/malta: Trace FPGA LEDs/ASCII display updates
The FPGA LEDs/ASCII display is mostly used by the bootloader
to show very low-level debug info. QEMU connects its output
to a character device backend, which is not very practical
to correlate with ASM instruction executed, interrupts or
MMIO accesses. Also, the display discard the previous states.

To ease bootloader debugging experience, add a pair of trace
events. Such events can be analyzed over time or diff-ed
between different runs.
