    powerpc/pseries: Update the device tree correctly for drconf memory add/remove · 3c3f67ea
    Nathan Fontenot authored
    This updates the device tree manipulation routines so that memory
    add/remove of lmbs represented under the
    ibm,dynamic-reconfiguration-memory node of the device tree invokes the
    hotplug notifier chain.
    
    This change is needed because of the change in the way memory is
    represented under the ibm,dynamic-reconfiguration-memory node.  All lmbs
    are described in the ibm,dynamic-memory property instead of having a
    separate node for each lmb as in previous device tree layouts.  This
    requires the update_node() routine to check for updates to the
    ibm,dynamic-memory property and invoke the hotplug notifier chain.
    
    This also updates the pseries hotplug notifier to be able to gather information
    for lmbs represented under the ibm,dynamic-reconfiguration-memory node and
    have the lmbs added/removed.
