v1:
1. Add PCIe PHY, CFG, and MMIO window support for AST2600.
Note: Only supports RC_H.
2. Add PCIe PHY, CFG, and MMIO window support for AST2700.
Note: Supports 3 RCs.
v2:
1. Introduce a new root port device.
2. For AST2600 RC_H, add the root device at 80:00.0 and a root port at 80.08.0
to match the real hardware topology, allowing users to attach PCIe devices
at the root port.
3. For AST2700, add a root port at 00.00.0 for each PCIe root complex to match
the real hardware topology, allowing users to attach PCIe devices at the
root port.
v3:
1. Fix review issues.
2. update functional test for the e1000e network card.
3. update license header
4. Adding "Based on previous work from Cedric Le Goater, with Jamin's summary
implementation.
v4:
1. Initialize pointers to NULL when declaring them.
2. Use distinct variable names to resolve memory leak issues.
3. Update functional tests to verify assigned IP addresses from
Intel NIC Ethernet interfaces.
4. Introduce pcie_mmio_alias in AspeedSoCState instead of dynamically
allocating memory.
v5:
1. fix memory leak issue. Replace g_autofree with array.

Testing the PCIe Root Complex model with the e1000e PCIe device
AST2600 test environment
Test image: ASPEED SDK v09.07
Download
https://github.com/AspeedTech-BMC/openbmc/releases/download/v09.07/ast2600-default-obmc.tar.gz
When booted, lspci should show one root device at 80:00.0 and a root
port at 80:08.0, matching the expected hardware topology:
```
root@ast2600-default:~# lspci
80:00.0 Host bridge: ASPEED Technology, Inc. Device 2600
80:08.0 PCI bridge: ASPEED Technology, Inc. AST1150 PCI-to-PCI Bridge
```
The e1000e driver is included in this image. Attach the e1000e device on
bus pcie.0 with the following command line:
```
-device e1000e,netdev=net0,bus=pcie.0 \
-netdev user,id=net0,hostfwd=:127.0.0.1:3222-:22,hostname=qemu0 \
```
After boot, lspci should show the e1000e device enumerated at 81:00.0:
```
root@ast2600-default:~# lspci
80:00.0 Host bridge: ASPEED Technology, Inc. Device 2600
80:08.0 PCI bridge: ASPEED Technology, Inc. AST1150 PCI-to-PCI Bridge
81:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection
```
The e1000e driver should probe successfully, and a new Ethernet interface
should appear:
```

AST2700 test environment
Test image: ASPEED SDK v09.07
Download
https://github.com/AspeedTech-BMC/openbmc/releases/download/v09.07/ast2700-default-obmc.tar.gz
By default, the ASPEED SDK only enables PCIe root complex 2 (RC2). If you
want to test all three PCIe root complexes, please use the customized
image provided here:
https://github.com/jamin-aspeed/openbmc/releases/download/qemu-test-0907/ast2700-default-pcie-qemu.tar.xz
When booted, lspci should show one root port at 00:00.0 on the
pcie.2 bus. The domain for PCIe RC2 is 0002, which matches the
expected hardware topology:
```
root@ast2700-default:~# lspci
0002:00:00.0 PCI bridge: ASPEED Technology, Inc. AST1150 PCI-to-PCI Bridge
```
The e1000e driver is included in this image. Attach the e1000e device to
bus pcie.2 using the following command line:
```
-device e1000e,netdev=net0,bus=pcie.2 \
-netdev user,id=net0,hostfwd=:127.0.0.1:3222-:22,hostname=qemu0 \
```
After boot, lspci should show the e1000e device enumerated at
0002:01:00.0:
```
root@ast2700-default:~# lspci
0002:00:00.0 PCI bridge: ASPEED Technology, Inc. AST1150 PCI-to-PCI Bridge
0002:01:00.0 Ethernet controller: Intel Corporation 82574L Gigabit Network Connection

The e1000e driver should probe successfully, and a new Ethernet interface
should appear:
