PCI/PCIe can access control by IOMMU that the virtualiztion and userspace driver will more safety. PCI/PCIe device could hot plugging, no design modifications SoC required, PCI/PCIe on Embedded SoC is popular now. We make a simple framework to support them. Feature Lists: 1.PCI INTx: the INT[A-D] pin IRQ for legacy PCI, work with platform PIC. 2.MSI/MSI-X: the message write IRQ for PCIe, work with platform's PIC. 3.PME: we only support the D0, D1, D2, D3HOT, D3COLD init by framework. 4.Endpoint: a simple EP framework for PCI FPGA or NTB function. 5.OFW: we only support work on OFW SoC, ACPI support in the future maybe. Host controller: 1. Common PCI host controller on ECAM. 2. Generic PCI host controller on ECAM. Signed-off-by: GuEe-GUI <2991707448@qq.com>
