Subject: [PATCH V2 0/5] accel/amd_vpci: Add new driver for AMD Versal PCI

This patchset introduces a new Linux Kernel Driver, *versal-pci*,  for AMD
Embedded+ platform.

The AMD Embedded+ platform integrates AMD Ryzen Embedded processors with
AMD Versal AI Edge adaptive SoCs on a single PCB [1]. The AMD Ryzen
Embedded processor is connected to the Versal AI Edge adaptive SoC via PCIe
enabling a tightly coupled heterogeneous compute platform. AMD Embedded+
platform is used for sensor fusion, AI inferencing, industrial networking,
control, and visualization.

AMD Versal PCI driver, versal-pci, is a host-side PCIe driver for AMD
Embedded+ platform running on AMD Ryzen Embedded processor.

The versal-pci driver is responsible for the management-plane operations
for the AMD Versal AI Edge adaptive SoC, including:

 - Loading accelerator firmware images
 - Reset and recovery
 - Health monitoring

The driver is licensed under GPL-2.0.

The firmwares are distributed as closed binaries. Please see [1] for more
information. Please see [2] for software architecture.
