Convert PPCE500Params to PCCE500MachineClass which it essentially is, and introduce PCCE500MachineState to keep track of E500 specific state instead of adding global variables or extra parameters to functions when we need to keep data beyond machine init (i.e. make it look like typical fully defined machine). It's pretty shallow conversion instead of currently used trivial DEFINE_MACHINE() macro. It adds extra 60LOC of boilerplate code of full machine definition. The patch on top[1] will use PCCE500MachineState to keep track of platform_bus device and add E500Plate specific machine class to use HOTPLUG_HANDLER for explicitly initializing dynamic sysbus devices at the time they are added instead of delaying it to machine done time by platform_bus_init_notify() which is being removed. 1) <1523551221-11612-3-git-send-email-imammedo@redhat.com> Signed-off-by: Igor Mammedov <imammedo@redhat.com> Suggested-by: David Gibson <david@gibson.dropbear.id.au> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
