This series is now ready to be merged, all of the patches are reviewed
and tested.
Palmer can you take this with all the other RISC-V patches sent during
the freeze?
V8:
- Drop SiFive U support
- Drop legacy -nic support
- Small other review changes
V7:
- Fix the GPEX memory mapping thanks to Bin Meng
- Fix the interrupt mapping thanks to Logan Gunthorpe
V6:
- Fix the interrupt issue for the GPEX device
V5:
- Rebase
- Include pci.mak in the default configs
V4:
- Fix the spike device tree
- Don't use stdvga device
V3:
- Remove Makefile config changes
- Connect a network adapter to the virt device
V2:
- Use the gpex PCIe host for virt
- Add support for SiFive U PCIe
Alistair Francis (4):
hw/riscv/virt: Increase the number of interrupts
hw/riscv/virt: Adjust memory layout spacing
hw/riscv/virt: Connect the gpex PCIe
riscv: Enable VGA and PCIE_VGA
