[PATCH openbmc 0/2] Add palmetto target to runqemu

[OpenBMC Patches]

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.

There's no networking, but I'll be taking a look at how difficult adding some
support might be. I've also asked in #yocto about if there's a better way to
add the palmetto support to runqemu but haven't had a reply. I'll ask on the
mailing list if that query goes unanswered, but from the way the scripts are
written it doesn't look like there is much alternative.

Cheers,

Andrew

PS: qemu doesn't terminate if you `poweroff`. To kill it, issue 'Ctrl-A c' to
switch to the monitor, then 'quit'.

Since the initial RFC:

  * Split the patch in two: add qemu_git.bb, then modify runqemu
  * Don't supplant yocto-poky qemu_2.4.0.bb
  * Change qemu_git.bb's fetch URL to avoid failures and add flexibility
  * Add a note about invoking `runqemu palmetto` on oe-init-build-env
