I was hoping to get some suggestions on how to handle using aliases to set linux,stdout-path.
* Do we want this protected via some board CONFIG? - should this be mutually exclusive with OF_STDOUT_PATH? - if so, which has precedence? * Was figuring we'd use CONFIG_CONS_INDEX to find the proper alias
any other comments are welcome.. this patch is a hack that works right now.
