This patchset introduces a new Linux Kernel Driver, amd-vmgmt for AMD Alevo
Versal based PCIe Card. The driver is based on Linux fpga driver framework.

The AMD Alevo Versal based PCIe Card, including V70, is the first Alevo
production card leveraging AMD XDNA architecture with AI Engines. It is
designed for AI inference efficiency and is tuned for video analytics and
natural language processing applications [1].

This amd-vmgmt driver provides services, including:
  - leveraging linux firmware and FPGA framework to download management
    firmware
  - program additional bit-streams for AMD Xilinx specific hardware
  - communicate with PCIe user function
  - communicate with firmware running on the PCIe Card
  - monitor device health

The driver is licensed under GPL-2.0 except for UAPI header which is
licensed GPL-2.0 WITH Linux-syscall-note.

The firmware and bit-streams are distributed as a closed binary, delivered
by AMD. Please see [1] for more information.

Your patchset is not correctly threaded. Please use proper --cover-letter
