[Qemu-devel] [PATCH v2 0/4] tighten conditions for board-implied FDC in pc-q35-2.4+

[Laszlo Ersek <lersek@redhat.com>]

Version 2 of
<http://lists.nongnu.org/archive/html/qemu-devel/2015-05/msg05640.html>.

Changes are broken out per-patch; the cumulative changes are:
- more granular structure (several patches in place of 1),
- rename "force_fdctrl" parameter to "create_fdctrl",
- drop the separate compat knob "force_fdctrl", use the "no_floppy"
  machine class setting in its stead (in inverse meaning).

I didn't touch ACPI bits (raised by Gabriel) because I got the
impression that they are
- alright on PIIX4 (which sees no change in this series), and
- already handled correctly / dynamically on Q35 (an independent issue
  was discovered but Gerd took that on, thanks).

Sorry if I misunderstood.

Thanks
Laszlo

  i386/pc: pc_basic_device_init(): delegate FDC creation request
  i386/pc: '-drive if=floppy' should imply a board-default FDC
  i386/pc_q35: don't insist on board FDC if there's no default floppy
  i386: drop FDC in pc-q35-2.4+ if neither it nor floppy drives are
    wanted
