My idea was to migrate each arch to the 'pure processing loops'
implementation I have just posted for x86. We can then factor out the
processing loop code into common code leaving just the init function arrays
in arch/foo/lib/board.c

We can then look at how to deal with the disparate init sequences - I'm
going to have a look at my new 'initcall' proposal to see if that is viable
- If so, we auto generate init_sequence.c

Regards,

Graeme
