Not until after I did the code and started to write the message
did I start to look at the other OS type boots.
Then I realized that the RTEMS bootm is just what I need. So
instead of adding a whole new type just change RTEMS to a generic
OS type, that may not care about the args.

So just change the function names and printf to make it obvious
it is a simple OS type. Also do a fall through case for both
RTEMS and GENERIC OS image types.

Here is an incomplete patch of what I mean.
