config, _IO_Initialize_all_drivers

[Heinz Junkes]

I'm still trying to get the booting and registering and initialising of the i2c devices on the MVME3100 to work properly.

In confdefs/iodrivers.h the driver address table is built up and then 
_IO_Initialize_all_drivers() is called without registering the individual devices first.

If I now enter in already before in bspstart.c

RTEMS_SYSINIT_ITEM(
  mvme3100_i2c_initialize,
  RTEMS_SYSINIT_BSP_PRE_DRIVERS,
  RTEMS_SYSINIT_ORDER_MIDDLE
);

a device (register it and e.g. got the major number 0) this is ignored by the IO_Initialize_all_drivers().

Shouldn't initialisation be preceded by registration ( rtems_io_register_driver() )?
