[RFC PATCH openbmc v3 0/8] Add palmetto target to runqemu, with networking

[Andrew Jeffery]

Hi all,

The patches modelling a bare-bones AST2400 in QEMU have been merged into
master for the upcoming 2.6 release. Attached is an attempt at integrating the
necessary bits into openbmc so we can `bitbake obmc-phosphor-image` then
`runqemu palmetto` to boot the BMC kernel and some representation of the
userspace.

This revision includes support for slirp and tun/tap networking: The machine
will come up at either 10.0.2.15 or 192.168.7.2 respectively. Note that the
network controller modelled is a Cadence GEM and not the ftgmac device, which
is a little inaccurate but means we can have networking sooner rather than
later.

The patches are also available on Github:

  https://github.com/amboar/openbmc/commits/runqemu-palmetto

I'd appreciate some testing and comments. I'm not sure about the approach of
baking in the Cadence driver for both environments (hardware, qemu) for
instance. Maybe we should use a different bitbake target altogether?

Cheers,

Andrew
