As I said, the search algorithm only works with a sorted table - just
what "sort_main_extable" does in Linux.  To be honest I did not look
too hard but I couldn't find anything similar in U-Boot so the table
will be unsorted and thus very likely fail if more entries are added.

So either sorting the table at some point or instead doing a linear
search would fix the problems.


It's very important  that you sleep because that's  when your brain is
garbage  collecting.  And a  dream is  if you  are interrupted  in the
middle and have junk left in the registers.
