PCI CAN interface emulation updated for QEMU 2.4

[Pavel Pisa]

Hello everybody,

the project implements simple CAN SJA1000 interface emulation
with option to connect emulated CAN buses to host system
SocketCAN bus. Project has been started by Jin Yang in frame
of RTEMS provided GSoC 2013 slot.

Code has been cleaned and is maintained to be up-to
date with actual QEMU releases. I would be happy to
follow suggestions and review for its possible
mainlining if there is interrest. If preferred,
I send patches inline to QEMU list.

Code is available from

https://github.com/CTU-IIG/qemu/tree/can-pci

The "can-pci" branch has been updated for QEMU-2.4 now.
The previous 2.3 support moved on "can-pci-2.3" branch.
Older support and support for PCI MF624 data acquisition
card can be found on merged branches merged-2.1,
merged-2.3 and merged-2.4.

    CAN bus simple SJA1000 PCI card emulation for QEMU

    The work is based on Jin Yang GSoC 2013 work funded
    by Google and mentored in frame of RTEMS project GSoC
    slot donated to QEMU.

    Rewritten for QEMU-2.0+ versions and architecture cleanup
    by Pavel Pisa (Czech Technical University in Prague).

    The core SJA1000 support is independent of provided
    PCI board. The simple core CAN bus infrastructure
    is independent as well.

    Connection to the real host CAN bus network through
    SocketCAN network interface is available for Linux
    host system as well.
