pls send vN+1 as a new thread not as a reply

this is "code duplication" not "double counting".

Random typos and trivial things. No need to repost until somebody
does a more substantive review.

Capitalize
Add a new PCIe endpoint function driver that works as a pci virtio-console
device. The console connect to endpoint side console. It enables to
communicate PCIe host and endpoint.
Architecture is following:
┌┐ ┌──┬┐
│virtioe │ │
PCIe endpoint framework provides APIs to implement PCIe endpoint function.
This framework allows defining various PCIe endpoint function behaviors in
software. This patch extend the framework for virtio pci device. The
virtio is defined to communicate guest on virtual machine and host side.
Already it has beed defined a config changed flag of ISR, but not the queue
flag. Add a macro for it.

The Linux PCIe Endpoint framework supports to implement PCIe endpoint
functions using a PCIe controller operating in endpoint mode.
It is possble to realize the behavior of PCIe device, such as virtio PCI
device. This patch introduces a setof helper functions and data structures
to implement a
