#     powerpc/powernv: Add queue mechanism for early messages
#     
#     When issuing a BMC soft poweroff during IPL, the poweroff can be lost
#     so the machine would not poweroff.
#     
#     This is because opal messages can be received before the opal-power
#     code registered its notifiers.
#     
#     Fix it by buffering messages. If we receive a message and do not yet
#     have a handler for that type, store the message and replay when a
#     handler for that type is registered.
