hw/pci-host/aspeed: Add MSI support and per-RC IOMMU address space

Add MSI support to the ASPEED PCIe RC/Config model and introduce a per-RC
"IOMMU root" address space to correctly route MSI writes.

hw/pci-host/aspeed: Add MSI support and per-RC IOMMU address space

Add MSI support to the ASPEED PCIe RC/Config model and introduce a per-RC
"IOMMU root" address space to correctly route MSI writes.

On AST2700 all RCs use the same MSI address, and the MSI target is PCI
system memory (not normal DRAM). If the MSI window were mapped into real
system RAM, an endpoint's write could be observed by other RCs and
spuriously trigger their interrupts. To avoid this, each RC now owns an
isolated IOMMU root AddressSpace that contains a small MSI window and a
DRAM alias region for normal DMA.

The MSI window captures writes and asserts the RC IRQ. MSI status bits
are tracked in new H2X RC_H registers (R_H2X_RC_H_MSI_EN{0,1} and
R_H2X_RC_H_MSI_STS{0,1}). Clearing all status bits drops the IRQ. The
default MSI address is set to 0x1e77005c and can be overridden via the
msi-addr property.

This keeps MSI traffic contained within each RC while preserving normal
DMA to system DRAM. It enables correct MSI/MSI-X interrupt delivery when
multiple RCs use the same MSI target address.

hw/pci-host/aspeed: Add AST2600 PCIe config and host bridge

Introduce PCIe config and host bridge model for the AST2600 platform.

This patch adds support for the H2X (AHB to PCIe Bus Bridge) controller
with a 0x100 byte register space. The register layout is shared between
two root complexes: 0x00–0x7f is common, 0x80–0xbf for RC_L, and 0xc0–0xff
for RC_H. Only RC_H is modeled in this implementation.

The RC_H bus uses bus numbers in the 0x80–0xff range instead of the
standard root port 0x00. To allow the PCI subsystem to discover devices,
the host bridge logic remaps the root bus number back to 0x00 whenever the
configured bus number matches the "bus-nr" property.

New MMIO callbacks are added for the H2X config space:
- aspeed_pcie_cfg_read() and aspeed_pcie_cfg_write() handle register
accesses.
- aspeed_pcie_cfg_readwrite() provides configuration read/write support.
- aspeed_pcie_cfg_translate_write() handles PCIe byte-enable semantics for
write operations.

The reset handler initializes the H2X register block with default values
as defined in the AST2600 datasheet.

Additional changes:
- Implement ASPEED PCIe root device (TYPE_ASPEED_PCIE_ROOT).
- Implement ASPEED PCIe root complex (TYPE_ASPEED_PCIE_RC).
- Wire up interrupt propagation via aspeed_pcie_rc_set_irq().
- Add tracepoints for config read/write and INTx handling.

hw/pci-host/aspeed: Add AST2600 PCIe PHY model

This patch introduces an initial ASPEED PCIe PHY/host controller model to
support the AST2600 SoC. It provides a simple register block with MMIO
read/write callbacks, integration into the build system, and trace events
for debugging.

Key changes:

1. PCIe PHY MMIO read/write callbacks
Implemented aspeed_pcie_phy_read() and aspeed_pcie_phy_write() to
handle 32-bit register accesses.

2. Build system and Kconfig integration
Added CONFIG_PCI_EXPRESS_ASPEED in hw/pci-host/Kconfig and meson
rules.
Updated ASPEED_SOC in hw/arm/Kconfig to imply PCI_DEVICES and select
PCI_EXPRESS_ASPEED.

3. Trace events for debug
New tracepoints aspeed_pcie_phy_read and aspeed_pcie_phy_write allow
monitoring MMIO accesses.

4. Register space and defaults (AST2600 reference)
Expose a 0x100 register space, as documented in the AST2600 datasheet.
On reset, set default values:
PEHR_ID: Vendor ID = ASPEED, Device ID = 0x1150
PEHR_CLASS_CODE = 0x06040006
PEHR_DATALINK = 0xD7040022
PEHR_LINK: bit[5] set to 1 to indicate link up.

This provides a skeleton device for the AST2600 platform. It enables
firmware to detect the PCIe link as up by default and allows future
extension.

target/hppa: Add emulation of a C3700 HP-PARISC workstation

This series adds a new PA-RISC machine emulation for the HP-PARISC
C3700 workstation.

The physical HP C3700 machine has a PA2.0 (64-bit) CPU, in contrast to
the existing emulation of a B160L workstation which is a 32-bit only
machine and where it's Dino PCI controller isn't 64-bit capable.

With the HP C3700 machine emulation (together with the emulated Astro
Memory controller and the Elroy PCI bridge) it's now possible to
enhance the hppa CPU emulation to support the 64-bit instruction set
in upcoming patches.

ppc/pnv: Add support for PHB5 "Address-based trigger" mode

When the Address-Based Interrupt Trigger mode is activated, the PHB
maps the interrupt source number into the interrupt command address.
The PHB directly triggers the IC ESB page of the interrupt number and
not the notify page of the IC anymore.
