How would that reduce the size of the code?

And, does it still work on all boards?

I think you don't understand the complexity yet. One problem we  have
to  solve  is  to make sure we have a very specific sequence in which
the init routines are run. The original idea of the code was that you
can #define the init_sequence[] table in an architecture and/or board
config file; it's just that nobody implemented that yet.

If you changed the code in this direction, then this might actually
make sense.

The Linux way of doing initcalls is useless for U-Boot, as it addres-
ses a completely different problem  and  is  based  on  a  completely
different memory management model.



Best regards,

Wolfgang Denk
