Controlling the order of driver initialization

Occasionally drivers need to control the order in which they are loaded, usually because one driver has a dependency on another driver. DDI drivers specify this in their Master(DSP/4dsp) files:

All DDI 8 and loadable drivers

Populate the ``$depend'' field in the Master file. For example, if the Master file for Driver A contains $depend B, the Driver B will be initialized before Driver A.

Pre-DDI 8 statically-loaded drivers

Set the ``order'' field in the Master file to a non-zero value to specify the sequence in which the module's init( ) and start( ) routines are called. Higher-numbered positive values are initialized before lower values.
