Hi all,

I've updated the QEMU virtio-msg branch, mainly by adding documentation for the virtio-msg-bus AMP PCI device.

In the process of updating the documentation, I started to question the value of the multi-FIFO support in QEMU. It may just add confusion, and the Linux driver doesn't support it yet. So I chose to remove it and leave that for future work.

Here's the branch and the relevant spec files: https://github.com/edgarigl/qemu/tree/edgar/virtio-msg-rfc

virtio-msg-bus AMP PCI spec (temporary location): https://github.com/edgarigl/qemu/blob/edgar/virtio-msg-rfc/docs/system/devic...

QEMU virtio-msg AMP PCI device usage: https://github.com/edgarigl/qemu/blob/edgar/virtio-msg-rfc/docs/system/devic...

Let me know if you have any comments.

Best regards, Edgar
