No worries, I just copied the commands from my history, some were sent
from Richard.  I hope they can help others in the future.

Last time I sent a patch Jia Liu also asked me to be maintainer,  I
added myself for now.  I am sure there are more qualified people like
Richard, but Ill try to help where I can.

Done.  If I do any more cool things with qemu I will post them to the
twiki.  Also, Ill try to link back to any docs I/we put on openrisc.io.

BTW, for now the image at 'Testing/System_Images' is hosted on my
server.  Would it be possible for someone to move it to the wiki or a qemu
server?  The link I posted should be up most of the time, but its not
something I would give any 9's of up time.
