-watchdog NAME is now equivalent to -device NAME, except it treats option argument '?' specially, and supports only one watchdog. A side effect is that a device created with -watchdog may now receive a different PCI address. i6300esb is now available on any machine with a PCI bus, not just PCs. ib700 is still PC only, but that could be changed easily. The only remaining use of struct WatchdogTimerModel and watchdog_add_model() is supporting '-watchdog ?'. Should be replaced by searching device_info_list for watchdog devices when we can identify them there. Also fixes ib700 not to use vm_clock before it is initialized: in wdt_ib700_init(), called from register_watchdogs(), which runs before init_timers(). The bug made ib700_write_enable_reg() crash in qemu_del_timer(). Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
