[Qemu-devel] [PATCH v3 0/5] fw-cfg: docs, cleanup, and user-provided cmdline blobs

["Gabriel L. Somlo" <somlo@cmu.edu>]

Document and clean up fw_cfg; additionally, allow user-provided blobs to
be inserted into fw_cfg via the qemu command line.

Changes since v2:

    - entire series depends on (applies on top of) another fw_cfg patch:
      (http://lists.nongnu.org/archive/html/qemu-devel/2015-03/msg04278.html)
      which is currently queued for 2.3.0-rc.

    - documentation (1/5) is now correct about all architectures using
      fw_cfg revision 0x1 :)

    - patches 2/5, 3/5, and 4/5 are unchanged

    - patch 5/5 (command-line insertion of fw_cfg blob) is now using
      qemu_opts_foreach() after machine_init, and is therefore
      compliant with -writeconfig and -readconfig (thanks again Laszlo,
      Gerd, and Markus for the quick tutorial!).
      Also, ee additional comments below the commit log in the actual
      patch message.

Thanks,
  Gabriel
