How would you do this, then?  To  pass  this  information  you  would
probably create the custom tags discussed earlier, right?

I'm not so sure. Keep in mind that the bd_info structure  comes  from
the  PowerPC architecture, wher eit is (more or less directly) passed
to the Linux kernel. For ARM it is not such a natural thing  to  use.
And  in  the  long run (when PPC finally starts using bi_recs) it may
disappear there, too.
