These two patches add support for the message log, and expose a new OPAL call called opal_invalid that allow me to cause OPAL to inject messages into the log.
The naming is a bit mixed, as our device tree node is opal-memcons and I retained the naming of the header structure 'struct memcons', but all other references are to the OPAL message log. They have been tested on a POWER7+ machine running some recent firmware.
