13.2: Initialization

IDE Controller chips used by a BSP are statically configured into IDE_Controller_Table. The ide_controller_initialize routine is responsible for initialization of all configured IDE controller chips. Initialization order of the chips based on the order the chips are defined in the IDE_Controller_Table.

The following actions are performed by the IDE Controller driver initialization routine:

rtems_device_driver ide_controller_initialize(
  rtems_device_major_number  major,
  rtems_device_minor_number  minor_arg,
  void                      *arg
)
{
   for each IDE Controller chip configured in IDE_Controller_Table
     if (BSP dependent probe(if exists) AND device probe for this IDE chip
        indicates it is present)
       perform initialization of the particular chip
       register device with configured name for this chip
}
