Support AMD CDX bus, for FPGA based CDX devices. The CDX
devices are memory mapped on system bus for embedded CPUs.

It uses sysfs interface and the vfio-cdx driver to discover
and initialize the CDX devices.

The patches are intended for DPDK 23.07 release, and have been sent
as an RFC as patches are yet to be merged in Linux.

Linux CDX bus patches has been submitted at:
https://lore.kernel.org/lkml/20230117134139.1298-4-nipun.gupta@amd.com/T/

CDX is a Hardware Architecture designed for AMD FPGA devices. It
consists of mechanism for interaction between FPGA, Firmware and
the APUs (Application CPUs).
Firmware resides on RPU (Realtime CPUs) which interacts with
the FPGA program manager and the APUs. The RPU provides memory-mapped
interface (RPU if) which is used to communicate with APUs.

VFIO CDX driver provides the CDX device resources like MMIO and interrupts
to map to user-space. DPDK CDX bus uses sysfs interface and the vfio-cdx
driver to discover and initialize the CDX devices for user-space
applications.

Nipun Gupta (6):
  bus/cdx: introduce cdx bus
  bus/cdx: add dma map and unmap support
  bus/cdx: add support for MSI
  bus/cdx: support plug unplug and dev iterator
  bus: enable cdx bus
  config/arm: add AMD CDX
