+commit a028dd423ee6dfd091a8c63028240832bf10f671
+
+    ppc/xics: introduce ICP DeviceRealize and DeviceReset handlers
+    
+    This changes the ICP realize and reset handlers in DeviceRealize and
+    DeviceReset handlers. parent handlers are now called from the
+    inheriting classes which is a cleaner object pattern.
+   
+
+
+The parent class (ie, TYPE_ICP) doesn't implement DeviceClass::reset(). It directly registers a reset handler with qemu_register_reset() instead. This is needed for cold plugged ICPs to be reset during machine reset since they're not SysBus devices.
+
+Cedric's patch missed that, but rather than reverting it, I'd rather go forward and:
+- introduce an abstract TYPE_ICP_BASE class that implements DeviceClass::reset()
+- have the current TYPE_ICP and all other specialized ICP types to derive from TYPE_ICP_BASE
+- have all specialized ICP types to register reset handlers with qemu_register_reset()
+
+This would match what was recently done with the ICS types.
