I thought we talked this through one day in Berkeley.

The idea is that platform-specific initialization occurs in  
PlatformInit. This includes things like clock calibration, IO pin  
configuration, etc. SoftwareInit is for general components. Since  
they can't start anything, generally the functionality there is  
pretty minimal.
