[PATCH] powerpc: Early debugging support for iSeries
Connect iSeries up to the standard early debugging infrastructure.
To actually use this you need to enable the iSeries early debugging
in setup_64.c. Then after the messages are logged hit Ctrl-x Ctrl-x on
your console to dump the Hypervisor console buffer.
